3D printing is also known as Additive Manufacturing (AM) and refers to printing processes used to create three-dimensional objects in which layers of material are formed under computer control. This is the latest craze in creative duplication / replication and so many creative geniuses here in Toronto are pushing the envelope everyday.
Among the innovators is Michael Gossack at My 3D Agency
My 3D Agency uses mobile scanning technology to do full body scans of our subjects in their desired pose. We take multiple scans to get the best possible data for the 3D prints.
Michael Gossack's 3D printing company is grass roots and entrepreneurial.
My 3D Agency specializes in duplicating props, people and equipment prototypes. Micheal made his name and grew his company from scratch on Toronto sidewalks by offering eight inch tall 3D selfies at very low prices. Today Michael spends most of his time putting fans' heads on their favourite superhero or sporting hero bodies and making custom wedding cake toppers. A graduate level print engineer, Michael at My 3D Agency team loves new challenges. Visit online or at his new location at 5 Dickens Street - Gerrard and Logan.
Michael's company scans, models and 3D prints the best 3D-figurines that you’ve ever laid your eyes on – and they’re photo realistic.
The organization uses more than just raw data to make their prints. At My 3D Agency, a graphic designer combines, edit and texturize all the data collected for a print-ready 3D model. Below is Raymi the Minx who had herself printed wearing the black spandex boots and skin tight dress seen below which Michael told her at the time was not entirely optimal for printing.
Once the file is ready, its uploaded into a final print software for last- minute fixes and positioning. In a few hours, the full- colour model comes to life. The nozzles add layer upon layer as the eight inch statue grows steadily taller and more defined.
When the model is finished printing, it goes through a few steps of post-processing and finishing – and is then ready to be shipped out.

In the last decade, cordless tools have expanded in voltage and application to become primary work tools on residential and commercial job sites. It's all because of the batteries.
Batteries are the backbone of the solar revolution. Fuel Ghoul notes that here in Toronto Canada, there are quite a few different service companies claiming to be 100% sustainable and new batteries with improved power storage technology are the keys to their success.
EcoDeckBuilder uses ‘solar powered’ cordless drills and chop saws to cut and join lumber (that has been ecologically sourced), and Ecocut Lawns offers ‘zero emissions grass-cutting using Greenworks lawn gardening power tools with lithium batteries.
In engineering, the term ‘battery’ refers to a device for making electrically charged atoms (ions) travel from one point to another through a power system. When electrical charges move, they create an electric current and it is this flow of ions that ‘powers’ things connected to the battery. Batteries are based on ionic chemistry. The chemistry of how elements and molecules take up / lose valence electrons to become charged / uncharged ions, and how ions are central to molecules and elements being able to dissolve into polar liquids (electrolytes), like acids, bases, and salts dissolved in water.
To physically make a battery you need two electrodes between which the ions will travel and in the middle of the cell, you need a substance for them to travel through, which is called an electrolyte. One electrode, called the anode is negatively charged. The other pole that’s positively charged is called the cathode. When the battery is discharging—i.e., when it’s connected to a device that draws power from it—positively charged ions shuttle from the anode to the cathode creating a current.

If you are looking at rechargeable batteries, just imagine plugging the device into a wall socket and pumping electricity back into the cells forces the ions in the electrolyte to shuffle back to the anode, where their potential energy is stored until needed again.
Almost everything in battery design comes down to the materials of which the device has been constructed. What is the anode made of? What is the cathode made of? And what is the chemical composition of the electrolytic medium in between? This chemistry determines how many ions the battery can store, and how fast it can pump them out as raw DC (direct current) power.
The First Batteries Were Made of Lead and Acid
The lead–acid battery was invented in 1859 by French physicist Gaston Planté and is the oldest type of rechargeable battery. Lead-acid batteries use Pb lead for the electrodes, and sulfuric acid H2SO4 is the electrolytic medium. Despite having a relatively low energy-to-weight ratio, and a low energy-to-volume ratio, its ability to supply high surge currents means that the cells have a decent power-to-weight ratio.
These features along with their low cost makes lead acid batteries attractive for use in motor vehicles which require a robust charge to start the internal combustion automobile engine. The modern starter motor needs a sustained 12-volt charge. The lead acid battery is not a very practical choice for portable equipment. I couldn’t imagine running a weed whacker or a cordless drill with a lead acid battery attached, as it would be heavy and dangerous.
Nickel Cadmium Batteries Versus Lithium batteries
The first Ni–Cd battery was created by Waldemar Jungner in Sweden in 1899, and like so many other electrical pioneers he had a patent dispute with the Edison Corp in the early 1900s which many people now believe Edison won only because he had greater financial resources to devote to the case.
The nickel–cadmium battery, NiCd battery or NiCad battery is a type of rechargeable battery using nickel oxide hydroxide and metallic cadmium as electrodes. The abbreviation Ni-Cd is derived from the chemical symbols of nickel (Ni) and cadmium (Cd), and interesting note - the abbreviation 'NiCad' is actually a registered trademark of SAFT Corporation which I believe is a direct descendant of the company that Jungner founded one hundred years ago.
Lithium Ion batteries were created at about the same time but it wasnt until the 1970s that breakthroughs made by Exxon funded labs made them feasible. Lithium ion has various formulas There are hundreds of formulas of lithium ion, each with various features and benefits.
Last decade, lithium-ion batteries gave transistor legs. Without the newly conceived lithium ion batteries developed by Exxon we would not have smartphones, tablets or laptops.
Lithium ion batteries do not necessarily bring more power to the job. Battery chemistry does not influence power - this calculation is determined by the voltage of the battery and the efficient design of the motor, transmission and mechanism at work. Increasing both or either voltage or efficiency increases power. An 18V lithium ion battery has the same potential to deliver power as an 18V NiCd battery because they are the same voltage. However, the ergonomic advantage of lithium ion batteries allows manufacturers to make higher voltage tools-and, thus, increase power-without increasing weight.
Lithium ion does not mean more run time The run time (or number of holes drilled on a single battery charge) is determined by three factors: 1. Battery voltage 2. Battery capacity (amp-hour) 3. Efficiency of tool design Increasing voltage, amp-hour or tool efficiency improves run time. NiCd and NiMH batteries range in capacity from 1.3Ah to 3.0Ah. In comparison, lithium ion batteries range from 1.1Ah to 3.0Ah. The lithium ion battery is smaller in size and lighter in weight than a nickel cadmium (NiCd) or nickel metal hydride (NiMH) battery. In addition, lithium ion has virtually no self-discharge. This allows a lithium ion battery to be stored for months without losing charge.
Remember, amp-hour is only one factor in run time, just as the size of the gas tank is only one factor in how far a vehicle can drive on a tank of gas. The best measure of run time on a cordless drill would be how many actual holes are drilled on a single charge, or how many boards were cut on a single battery. But even using these true metrics, the applications per battery charge factor in voltage, capacity and the efficiency of the tool and operator.
Its also worth noting that there currently is no industry standard for measuring the amount of recharges a user can get from the battery.
Memory Glass is a little different than normal glass because it contains a very special foreign substance: cremated human remains.
Memory Glass is a type of Funerary Glass
The term 'Memory Glass' refers to solid glass sculptures and keepsake jewelry that contains the cremated remains of friends, family and beloved pets. In these unique art pieces, bone ash is incorporated right into the glass mixture and appears as puffy white clouds under a transparent surface. Sometimes called Funerary Glass this art form is as old as the Romans and has come in and out of style for twenty centuries. Today in 2015, due to shrinking cremation service costs at Basic Funerals and other online undertakers, Memory Glass is coming back into mainstream funeral fashion.
Today beautiful memory glass centers on striking the perfect balance between art glass and the aggregate cremated material which does NOT bond with the glass itself but makes bubbles of white creamy clouds inside the piece. The article on how Cheaper Cremations Increases Funeray Glass on Digital Journal shows Angelo Rossi at Skylon Tower Niagara Falls at work making memory glass and also shows his various shapes, styles and stockpiles of the stuff.
The sifted ashes are delivered from the funeral home in a small glass jar, usually by the funeral director, complete with the paper tags bearing the name and number of the deceased.
Are there glass making chemical components inside human remains?
The Cremation Process is Very Efficient
Commercial crematoriums are designed to produce temperatures between 870–980 °C, though in some situations much higher temperatures are possible, depending on the configuration and off gassing designs. Larger bodies take longer, especially where there's excessive body fat. The time it takes to cremate a body depends primarily on the size of the body..
So what is left at the end? Bone ashes. We call them 'cremated remains' but its a fact that they are the non-burnable elements of the body. For the most part, this is just bones and teeth of the human skeleton.
Cremation temps of approx 800°C vaporizes almost all the tissue in the body, and what remains is the hardest most dense material.
Other things like dental and surgical prostheses may also remain in the ashes, and are usually sifted out of the powder along with larger bone fragments before the dust is delivered to the families of the deceased in a clear plastic bag.
The mineral in bone is hydroxylapatite, a type of calcium phosphate with the formula, Ca5(PO4)3(OH). But in the heat of cremation, it’s at least partly transformed into tricalcium phosphate, or Ca3(PO4)2.
The bone dust is delivered to the glassblower in a small glass jar with the official name and death certificate number of the deceased.
Technical difficulties of making memory glass with cremated remains
The technical difficulties of making memory glass with cremated human remains has a lot to due with expansion co efficiencies of ashes which are three times more expansive than soda lime material. If this foreign material had any density it would certainly crack the glass either while cooling or in future heating and cooling of the glass vessel.
When an object is heated or cooled, its length changes by an amount proportional to the original length and the change in temperature. Linear thermal expansion of an object can be expressed as
dl = L0 α (t1 - t0) (1) where, dl = change in length (m, inches) L0 = initial length (m, inches) α = linear expansion coefficient (m/moC, in/inoF) t0 = initial temperature (oC, oF) t1 = final temperature (oC, oF)
Eric Davy, funerary glassblower in Toronto and principal at Davy Glass specializes in making Memory Glass paperweights. When creating these art glass items he adds the cremated remains into the mix before the first gather, and as the powder expands in the glass it makes wonderful puffy white clouds.
But of course they weaken the glass - not that a paperweight has to be very strong. According to physics its important to note that if the paperweight were to be heated and then rapidly cooled it would break along lines made by the ashes inside.

Modern glass composition is 65% silica, 25% soda, 10% lime. Silica is the most common element on planet Earth. The oxide is SiO2 and is added to soda, Na2CO3 and lime.
Lime is a calcium-containing inorganic material in which carbonates, oxides and hydroxides predominate. Strictly speaking, lime is calcium oxide and or calcium hydroxide. It is also the name of the natural mineral (native lime) CaO.
Like most 'Hot Glass Artists' today, Eric Davy and his assistant Alex Wilson use Studio Nuggets delivered direct to the shop in the 50lb bags seen below.
Soda lime glass is the most common type of glass today, representing 80% of all commercial glass. This substance is extremely important in our day to day lives because it’s used everywhere, in windows, jars, jugs, bottles and drinking glasses. Art glass blowers who make Memory Glass generally buy and use Studio Nuggets soda lime glass pellets which promise the following composition of 60-75% silica , 12-18% soda, 5-12% lime and nothing else.
Eric Davy makes both funerary urns $900, and Memory Glass paperweights $200 es.

What's the difference between Laser and Intense Pulse Light or IPL when it comes to laser removal services?
LASER (light amplification by stimulated emission of radiation) is made up of light beams that are all the same size, a specific wavelength, and are focused together in a narrow channel.
Fuel Ghoul wrote about how lasers are used in dentistry when we profiled the Markham dentist with a powerful Biolase laser. A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. This pictures shows a very simple schematic outlining the basic concept.
But this is hard to do.. And because its such a complex achievement, there is some dispute about when Lasers were actually invented, but the Laserfest website says Theodore Maiman invented the world's first ruby laser in 1960.
Comprehending the Ruby Laser
Ruby crystal can be grown artificially. The gem is composed of aluminum oxide, where some of the aluminum atoms have been replaced with chromium atoms. So.. if I understand this correctly, regarding the picture on the right, in a ruby laser, the Gain Medium would be a ruby - grown artificially in a cylindrical tube. That cylindrical and hopefully mathematically perfect ruby is then wrapped in a light source which pumps massive amounts of light radiation into the crystal matrix.
Only a fraction of this energy escapes through the Gain Medium to the Output Coupler, which joins the light streams together into a single 'beam'. In early demonstrations of the ruby laser, the output is a single pulse because it takes so much energy to make the light required around the Gain Medium and its hot. Some sophisticated cooling apparatus around the crystal array is required esp for contiguous beam lasers.
Ruby lasers were among the first instruments developed, and publicly tested, and are used today in many applications including healthcare. Over the years, many thousands of scientists in various advanced nations have been working on improving the technology, and have improved the Gain Mediums. Lasers can now be divided into three categories: gas lasers, solid lasers and molecular lasers.
All three types of Lasers are frequently used in healthcare today.
Modern medical science uses lasers to diagnose disease and make precise incisions in human flesh. Eye surgeons harness lasers to correct vision. Dentists use lasers to do soft tissue oral surgery, and teeth whitening. Many other medical practitioners use some sort of photon scalpel to deliver light energy somewhere in the human body, and by using different wavelengths they can achieve different results. Most medical laser beams are so small, and so precise they allow doctors to safely treat diseased tissue without injuring the surrounding area.
Laser vein removal often uses radio frequency or laser energy to cauterize veins from the inside out..
Endovenous Ablation - Varicose Vein Treatment
Endovenous ablation is a treatment that uses radio frequency or laser energy to cauterize (burn) and close abnormally enlarged veins in the legs, a condition called varicose veins.
Normally, blood circulates from the heart to the legs via arteries and back to the heart through veins. Veins contain one-way valves which allow blood to return from the legs against gravity. If the valves leak, blood pools in leg veins which can become enlarged or varicose.
Endovenous ablation is an image-guided procedure that uses heat generated by radio frequency or laser energy to seal off these faulty vessels, diverting blood flow immediately to nearby healthy veins.
The heat kills the walls of the veins and the body then naturally absorbs the dead tissue and the abnormal veins are destroyed. It can be carried out in a simple treatment room rather than in the operating theatre.
Intense Pulse Light Therapy is not a Laser Therapy
Intense Pulse Light (IPL) systems work on the same principles as lasers in that light energy is absorbed into particular target cells with colour (chromophores) in the skin. The light energy is converted to heat energy, which causes damage to the specific target area. IPL systems are different to lasers in that they deliver many wavelengths (or colours) in each pulse of light instead of just one wavelength. Most IPL systems use filters to refine the energy output for the treatment of certain areas. This enhances penetration without using excessive energy levels and enables targeting of specific chromophores (these are skin components that absorb light).
IPL therapy is considered a non-ablative resurfacing technique, which means that it targets the lower layers of skin (dermis) without affecting the top layers of skin (epidermis). The results are not as dramatic as ablative resurfacing where both the dermis and epidermis are injured to produce a much more noticeable overall outcome. The advantage of IPL therapy is its minimal downtime – a patient can often have the procedure done in their lunch break and return to work immediately afterwards.
Lumecca IPL for Skin Rejuvenation
InMode Lumecca uses intense pulsed light to carefully target and treat skin conditions through selective photothermolysis. The Lumecca program improves the appearance of age spots, sun damage, vascular lesions, rosacea, and freckles. An improved skin appearance can be seen after the first session and multiple sessions deliver even better results. A strong sapphire-cooling tip provides a safe and painless procedure for clients. Lumecca can be combined with Fractora for a full-face treatment regime.
Selective photothermolysis is an optical technique used to ablate tissue in targeted regions. The objective is to heat targeted tissue with a laser and destroy it without damaging surrounding tissue. Targeted cells are damaged mainly through the absorption of light and the subsequent heating of tissue due to energy transfer. Heating of the tissue denatures proteins and halts major cell survival processes.
Skin tightening at Numi spa in Brampton shows the patient lying flat, protected with goggles and numbing gel, getting an IPL treatment at the hands of a skilled technician.
The clinic uses the InMode Lumecca machine which produces a high-output flash to produce a broad wavelength output of non coherent light between 500 to 1200nm. Light pulses generated by this device and others on the market are produced by bursts of electrical current passing through a xenon gas-filled chamber. Xenon is the new ruby. The lamp output is then directed toward the distal end of the hand piece which releases the energy pulse onto the surface of the skin via a sapphire block. So you see the elements of a laser are still present - a light source connected to a gain medium and then some manner of output synchronicity device. You can read more about Numi Spa Laser Removal in this Brampton magazine.
IPL is now among the most commonly used treatments for spider and thread veins, and some vascular birthmarks. Light pulses are targeted at the red-pigment (haemoglobin) in the blood which heats and destroys the pigment without affecting the skin or other tissues.
Bluechem Group is an automotive lubricants manufacturer based in Europe. They make and sell over four thousand different chemical products, in just about every country, all over the world.
In recent years, this corporation has been developing a lot of products for well-known automakers that contacted them because of their increasingly high tech demands. After comprehensive testing in their labs, Bluechem research scientists modify the right effectiveness and compatibility to the vehicle maker's specific parts. The CTP GmbH uses state-of-the-art lab facilities in Germany to do research on fuel cleaners using gas chromatography, material testing, emission measurement and oil or water analysis. The short distances between production, laboratory and technical decision-makers enable more effective work and research processes.
In 2006 the CTP GmbH was nominated for the Innovation Award of Thuringia for the joint project with the Fraunhofer Institute "Method and apparatus for removal of deposits in internal combustion engines" won a second prize.
On their website, Bluechem describes themselves as a medium-sized enterprise that's aware of their social responsibility. They write, "...we manufacture in Germany, fulfill our tax obligation and re-invest our company profits into research and development as well as into the expansion of our company sites. By supporting national and international charity projects we would like to make a contribution to make the world a better place."
Bluechem Canada is the exclusive dealer portal for Bluechem brand products in this nation. They have a unique challenge today here in North America to try and build presence in this crowded marketplace that's already full of legacy brands, dominated by big box retailers and existing automotive dealerships relationships.
Oil System Cleaners Extend Automotive Engine Life
Europeans better understand that simply changing the oil in your automobile is not a complete cleanse. It's a fact that a few hundred milliliters of used oil and sludge may remain in your engine after a traditional oil change. This sludge often has the worst and heaviest contaminants that could lead to mechanical breakdowns, premature engine failure, and costly repairs.
On Saturday, Fuel Ghoul traveled to North York Ontario to watch Ryan Wilford perform a product demonstration for Bluechem Oil System Cleaner.
Independent auto mechanic Chris Ko gave up his Saturday and his 2010 Honda Civic to Ryan Wilford for a few hours to run his compression tests - these were done before and after adding the Bleuchem product.
After dissembling the engine (twice), Chris and Ryan executed the compression tests using an analog Moto-meter test device. I wrote up the whole story of Ryan Wilford's product demo on Digital Journal, Bluechem brings engine Oil System Cleaner to Canada.
The two compression tests showed the powerful cleaning agent in the used motor oil has a 'healing' effect on the engine.
Before the additive, the number two and number four cylinders were doing one full bar less work, and after the product was added all cylinders can been seen doing almost one full bar more work! This reduces the discrepancies between cylinder strengths that can lead to engine shake and that peculiar wobble which is so common in older model cars and trucks.
Clean Automotive Fuel Systems Improve Fuel Flow
When a driver depresses the gas pedal in a modern automobile, they expect a peppy response; the pedal controls how much fuel and oxygen the engine receives and when depressed the driver expects immediate vehicular acceleration. But over time, carbon deposits can form in critical areas inside the fuel system, resulting in reduced fuel economy, and loss of power.
Periodic fuel system cleaning can help maintain optimal engine performance. The spray from the fuel injectors needs to be wide and fine for the spark to ignite it. Think of the way you want the nozzle of an aerosol spray can or hairspray to come out of the can — an even, fine mist. If the tiny nozzles on the fuel injectors get clogged, you get a gloppy stream instead. Engine performance is affected by everything from carbon deposits and corrosion to heat and friction.
There's advanced chemistry automotive engine cleaning products available to consumers that are not manufactured by major oil companies, or automakers, and as such they struggle for market share in a big box dominated auto parts aftermarket retail world.
Bluechem-Canada Ryan Wilford - Fuel System Cleaner
Direct injection fuel delivery systems are two decades old design innovations that are now almost universally embraced by automakers because of how injectors maximize engine performance, reduce fuel consumption and lower exhaust emissions.
Direct injection fuel deliver systems insert liquid and oxygen directly into the combustion chamber at a very high pressure, low volume and for very short period of time. A computer controls the intricacies and enables the engine to make significantly more power with reduced fuel consumption and less carbon emissions.
But a major downside is that direct injection engines are prone to carbon accumulation on the injectors that can significantly impact performance and fuel economy and nobody tells consumers. That story is only starting to come out now..
The January 1015 AutoGuide has a story, Is Carbon a Problem with Direct Injection Engines? in which the author Gregg Cole writes, “We’ve heard rumblings that blackened buildup on the backsides of intake valves is a major problem and something that could be disastrous for motorists in the coming years.”
Bluechem Fuel System Cleaner also removes carbon, gum, varnish, and other operationally caused contamination from the entire fuel system. It provides clean and powerful combustion reducing emissions. It binds water and moisture in the fuel system creating a stable combustible emulsion.. It lubricates and protects the entire fuel system. It wont harm senors opr impair the functionality of fuel filters.
You Don't Need To Be A Mechanic To Use Bluechem Fuel System Cleaner
Every 300ml bottle comes with a tiny red plastic funnel spout. With this in mind you might believe this handy Fuel System Cleaner dispenser is specially designed for home enthusiasts.
Bluechem Fuel System Cleaner Instructions: Use every 30,000kms service and oil change. Add to the fuel system. 300 ml (1 can) treats up to 80 litres (21 gallons) of gasoline.
The result is more power to the automobile, reduced emissions, and improved gas mileage. Chris Ko reported an immediate improvement in engine handling and performance.
The Rubber Rose was a famous sex shop in San Diego that YELP now reports as being closed. The image is kinky all the same, as rubber symbolizes sexual deviance and the red rose always means love. A genuine manifestation of this sexy symbol is exactly what Matthew Robert White was seeking when he commissioned Bill Korenowsky of Royal Waterproofing in his basement to buy roses and dip them in various chemical treatments until they found one that preserved the rose forever. Matt was seeking an nonperishable rose product he could sell for $5 each on Valentine's Day. You can read all about Matthew Robert White pop-up retail vision on Digital Journal.
There is something morbidly wonderful about desecrating red roses on Valentines Day, especially when we can use the latest waterproofing science to preserve them, and their contempt for this romantic tradition, forevermore.
Bill Korenowsky, who is getting married this year, is no stranger to florists. He knows just what red roses cost, and where to buy the best ones. He started with a dozen roses and ... well, he never really got one that was beautiful enough or 'rubber' enough for Matt to sell, but he had a lot of fun trying.
Basement Waterproofing Contractor Rose Treatments
Bill Korenowsky did his level best to find Matthew's rubber rose recipe. Here he is holding the best of his Bakor Aqua Bloc dipped roses which are hard as a rock today, but not very pretty.
Bill Korenowsky of Royal Waterproofing holds a Waterproofed Rose.
Bakor Aqua-Bloc® 770-06 is a one component elastomeric waterproofing compound designed to replace conventional hot mop felt ply and/or pre-formed sheeting systems. It's applied in a single application, which cures through solvent evaporation to provide a heavy-duty, seamless, rubber-like impervious membrane. This is a liquid applied waterproof product that is good for year round use.
Dipping the fresh red roses in the waterproofing compound was rather difficult as the mixture was not very viscous. It reminded me of axle grease and as such it was not liquid. and not quite solid, but consistent enough to give the fragile rose a tough time and the finish was not smooth or representative of the flower's true form. So indeed it was an abject failure. But Bill did try his best.
Excellent for use on concrete, masonry foundation walls, parking decks, planters and reflective pools, Bill combines this goop with Yellow Jacket reinforcing fabric to treat cracks and joints. The finished work is a heavy body trowel grade coating that provides a seamless rubberized asphalt membrane.
There is a video of Bill dipping roses in Waterproofing compound,
The idea of waterproofing roses is not to make black floral pieces but rather to preserve them in a substance that will make them beautiful forever. To be able to transform roses into floral statues is appealing to pop-up retailers and romantics alike, but the dipping experiment has proven unsatisfactory.
The Roses Need Hydrophilic Coatings Modern waterproof clothing and especially winter jackets are manufactured by spreading a thin layer of resin directly onto the inside face of the fabric, also known as a hydrophilic coating. Some fabrics are sprayed with a polyurethane coating before being made into a jacket and this is something Matt could try next. Polyurethane roses..? This is already a name for a type of crown molding.
Durable Water Repellency (DWR) is a waterproofing treatment that is sometimes sprayed onto fabric (and so could also be applied to flowers), but another way of coating fabric is to laminate or membrane over the surface to form a protective wall from water droplets on the outer layer. A chemical treatment, DWR is not waterproof, but does reduce condensation forming, aiding breath-ability. There is the possibility of 3D printing a protective sealant over a red rose and adding any pigment in any portion of the flower.
Fuel Ghoul loves chemistry in action! And we love to see new twists on tired 'civic cliches' that impose social expectations on young people. Take for example the ridiculose idea they need to give their lovers a dozen red roses on Valentine's Day, and turn it on its head.
This year SMOJoe worked alongside Dan Sheridan of ToughRoof flat roofing repair company in Toronto to make tar covered black roses for folks to give away, which really started the ball rolling and brought a lot of interest to this otherwise tired holiday subject. Eligible Magazine is featuring a story on Black Roses on Valentines Day this year. Turns out there's a lot of people sick and tired of giving red roses on that special day.
The act of coating objects with bitumen, especially wooden baskets, bowls, and boats, and even people in hot pitch (with a side order of chicken feathers) is thousands of years old. The word comes from 15th century Middle English bithumen meaning a mineral pitch, from Latin bitumin-, bitumen. This was used all over the country, and in the Royal Navy as watersealing agent and probably used for building projects and roofing jobs too.
Most people think flat roofing tar is made from coal tar, and there was a time when this was indeed the case. And if you ask them today, those same ill informed people think 'pitch' is made from pine tar, but these days its all made from petroleum bituman. Even with low oil prices the tar sands in Alberta is spewing out so much bitumen as a petroleum refining biproduct, it makes economic sense that this material be repurposed for other industries.
Websters Dictionary defines bitumen as 'a mixture of tarlike hydrocarbons derived from petroleum. Black or brown, it varies from viscous to solid; the solid form is usually called asphalt. Bitumen occurs in nearly every part of the world and in nearly the whole range of geologic strata. The term may also refer to synthetic hydrocarbon compounds'.
Bitumar comes in 20lb blocks and is heated to liquid in giant propane boilers that are towed behind vehicles.
The liquid petroleum bitumen is pumped to the roof direct from the boiler.
Behold a beautiful black rose that has been dipped in Petroleum bitumen is difficult to photograph because its so shiny and reflective.
This is how commercial roofers fix leaks and resurface flat roofs in Toronto, which is a cold weather climate with lots of rainfall that gets real hot in the summer. Its a challenging arena for roofers. Many roofs are made of a bitumen substructure thats covered with either tar paper or gravel. Liquid hot bitumen is sticky and makes excellent roofing tar that can be used to fix leaks in existing roofs or used as an adhesive to bond other material to fix a leaky roof. Since formulations for roofing tar vary by brand and type, it’s important to pick the right product.
Roofing tar is sensitive to temperature; temperatures lower than 70F means the substance will take a long time to set. However, in extremely high temperatures, roofing tar will turn into a liquid. Roofing tar’s unique liquid/solid properties make it ideal for flat and low slope roofs, where it can be self healing and fix leaks. However, roofing tar should not be used on high slope roofs, since it will turn liquid at high temperatures and drip off. Also, roofing tars should not be used on asphalt products or thinned with water or other solvents.
Dave from ToughRoof gave me lots of good information and was very accommodating as we delved even deeper in the art and science of black roses.
Roofing 'Bitumar' comes in solid ten pound blocks at room temperature. It gets delivered to the job as a black solid block that when heated to 500 degrees becomes an oily liquid used on flat roofs to fix leaks. It is made from coal tar and petroleum byproducts. Coal tar is a deep brown or black residue, which is made during coal production process. Coal tar must be refined and processed to meet standards for roofing use.
ToughRoof can make white roofs. Bitumar is black as molasses, but modern science is such that the colour can be altered in stages. The liquid material goes on hot and seals, bonds and repairs areas on the roof that damaged or are slowly deteriorating and then colour has options like white coating under white gravel or flagstones. Newer formulations of roofing tar are asbestos free, but may contain solvents, surface adherents, plastics and mineral fillers/fibers. Coal tar roof cement by contrast must be applied by trowel, while other types of roofing tars are applied like paint or caulk.
Some manufacturers have created silver and white products by which builders can deliver on a promise to make white roofs which have proven efficiencies. Some brands of roofing tar can be painted when dry to match the roof’s original color scheme. Roofing tar stains and drips and ugly mistrowels can be removed by using a tar remover, but be warned such removers may cause damage to paint and other membranes.

These black roses are certainly beautiful, and have inspired both pop-up holiday retailers and copy cats.
Matthew Robert White is also experimenting with wax roses and waterproof roses, or what were once red roses that have been dipped in a waterproofing compound that can be any colour. I've decided to do an entire write-up on that subject next week, closers to valentines Day as the waterproofing compound in another whooly original product of modern science.
The In & Out Car Wash in Brampton is a spa for automobiles of every description and offers all manner of services beyond the traditional offerings you might expect at a first class urban facility. This place is an absolute bastion of car waxes, air fresheners and tropical scented detergents. Proud car owners parade through a glass tube watching their vehicles get dried, waxed and thouroughly cleaned.
The main building offers custom waxes and auto detailing, but look here at the bottom of the list and see Oil Changes, Rustproofing and Emissions Tests? Huh .. At the car wash? Not quite. This sign refers to services offered at the adjoining Jiffy Lube.
A Jiffy Lube Signature Service® Oil Change is more than an oil change. It's a preventive maintenance program that enhances the reliability and longevity of your vehicle. It all starts when you drive your car or truck into authorized Jiffy Lube location. Here's an account of my experience on Friday Dec 19th 2014 getting an oil change in Brampton Jiffy Lube.
There is no appointment necessary at Jiffy Lube. Customers simply show up and wait for the work to be done, in a jiffy. They mindlessly surrender their keys to staff and then sit in a warm waiting room sipping free coffee, reading magazines and watching CP24 on a huge flat screen. They can always peer through the windows behind the counter and see their car being serviced in the garage, if so inclined.
At Jiffy Lube the cars come in the bay with warm engines, and that's good because the sludge will move out from around the working parts easier when the metal is hot. The car is driven into the bay by a staff member with another mechanic watching the tires and guiding the vehicle over the pit in the floor of the garage. Once the vehicle is parked, the emergency brake is applied and the front hood release is 'popped' open. Now the work begins.
The vehicle is identified, or registered into the Jiffy Lube database if its a first time customer. The staff member records the owner's name, address, license plate, and mileage information. They know what type of oil works best for every vehicle and stock all manner of fluids for cars. After the car has sat for a few minutes, the worker above checks the oil and records its levels and colour. At Jiffy Lube there is a basement pit and the workers down there are called 'pit jockeys' and they do the dirty work but have the brightest smiles. With the car parked above, the pit jockey uses a crescent wrench to loosen the oil plug He wears thick rubber gloves because that oil could be scalding hot. With a sheet of folded tin to catch the fluid over sliding tray with a mesh screen.
The main function of engine oil is to reduce wear on moving parts; they also clean, inhibit corrosion, improve sealing, and cool the engine by carrying heat away from moving parts. Motor oils are derived from petroleum-based and non-petroleum-synthesized chemical compounds. Motor oils today are mainly blended by using base oils composed of hydrocarbons, polyalphaolefins (PAO), and polyinternal olefins (PIO), thus organic compounds consisting entirely of carbon and hydrogen. The base oils of some high-performance motor oils however contain up to 20% by weight of esters.drains it from below The worker below removes the oil plug and the old oil drains away into a recycling tank below. In engines, there is some exposure of the oil to products of internal combustion, and microscopic coke particles from black soot accumulate in the oil during operation. Also the rubbing of metal engine parts produces some microscopic metallic particles from the wearing of the surfaces. Such particles could circulate in the oil and grind against the part surfaces causing wear.
The oil filter removes many of the particles and sludge, but eventually the oil filter can become clogged, if used for extremely long periods. They place a pan or container underneath the oil drain plug, loosen its bolt with your standard wrench, and remove the plug, being careful to keep your hands and other vitals out of the way of the stream of hot oil. It should take no more than ten minutes to drain the old oil completely, and when the dripping stops the pit jockey replaced the oil plug on the bottom of the car.
You can count on Jiffy Lube to use the recommended weight and amount of oil for your model of car. Change the oil with up to six (6) quarts of quality motor oil Double check on the oil change. Replace the cap, and in a few minutes, check to make sure your oil level falls between the low and full marks on the dipstick. Jiffy Lube will also replace the oil filter Here is the pit jockey applying a wrench to a Coke can-sized object found beneath the car.
The worker loosens and removes the air filter with the proper size oil-filter wrench, being careful not to drip oil on himself. He replaces the attachment, making sure to rub the new filter’s seal with a little oil and making sure its on tight (but NOT wrench tight).
The Jiffy Lube oil change specialists visually inspect the vehicle's antifreeze / coolant reservoir levels and engine air filter. They check the condition of the serpentine belts, the wiper blades and exterior lights. They also check brake fluid levels in their transparent reservoirs.
At Jiffy Lube the oil change technicians will also vacuum the interior floors of the vehicle. Clean exterior of windows Lubricate the chassis (when applicable)
The staff checks tire pressure and then checks and tops up the following fluids: - transmission/transaxle fluids - Differential/Transfer Case fluid - power steering fluid - windshield washer fluid - battery water (excluding sealed batteries) Bonus! You will also receive free top-offs on motor oil and any or all of these five vital fluids between service visits for up to 5,000 km.
Additionally, Jiffy Lube will perform a service review, which includes a visual inspection of the engine air filtration and the vehicle manufacturer's severe service* recommendations based upon the vehicle's current mileage. Not many people know there is a Jiffy Lube on the east side. back in the car wash.
In all automotive engines there is some exposure of the oil to products of internal combustion, and microscopic coke particles from black soot accumulate in the oil during operation. Also the rubbing of metal engine parts produces some microscopic metallic particles from the wearing of the surfaces. Such particles could circulate in the oil and grind against the part surfaces causing wear. The oil filter removes many of the particles and sludge, but eventually the oil filter can become clogged, if used for extremely long periods.
Oil changes are part of life, and now the In and Out Carwash facility in Brampton really is an all-in-stop full care automotive vehicle maitenance destination.
As food education improves, Canadians are becoming more health conscious, and are turning away from commercial baked breads to buy healthier cereal alternatives. 2012 Canadian bread sales statistics as reported in Financial Post shows many health conscious shoppers have stopped buying glutinous white bread at the supermarket because there are other more attractive bread alternatives 'rising up' in local markets. Among the most popular new choices are slow cooked sourdough breads made in artisan bakeries. These micro bakers are getting larger slices because they win on taste and health benefits.
Shasha Bread CEO Shaun Navazesh bakes with Sprouted Grains
We began our trek through this remarkable facility in the sprouted grains section of Shasha's large bakery.
ShaSha has been sprouting ancient grains since 1999. Today he sprouts Adzuki Beans, Mung Beans Lentils and Brown Rice which he dries and grinds into flour to make delicious sourdough breads. These organic ingredients are also sold separately in the Organic Food Store on the premises.
Sprouted grains, lentils and beans offer more Vitamin C to human digestive systems; the sprouting neutralizes the phytic acid in the seeds which means the vitamins and minerals in the meal are more readily absorbed by the body.
When the workers make sprouts in Shasha's specially designed high moisture chambers, they're actually starting the seed's germination process, which changes the chemical make-up of the biological package - Mother Nature's reproductive system kicks into gear to make a new organism.
Sprouting dramatically increases the amounts of vitamins and minerals in the lentils, especially B vitamins and carotene.
When sprouting grains to make sprouted grain flour, Shasha Bread company is careful not to allow the sprouts to grow too large. They begin dehydrating the grains shortly after the root tip appears.
To prepare for the next phase of this artisanal baking process, workers dry these activated grains using a fan in a dehydration room (not in the oven). The drying is slow and time consuming; days later these same grains and pods are collected and ground on stone wheels in a grist mill on site to become a wholesome 'sprouted flour' for baking.
Shasha Bread Company Grinds Their Own Sprouted Grains
Although the flour mill occupies only a small part of the bakery, its a very busy work station on most days as so many of Shasha bread recipes require some of the many types of flour made on site. Rich in fiber, antioxidants and essential nutrients, flour made from ancient grains such as quinoa and amaranth are rapidly gaining in popularity. Also consumption of blended flours is increasing among consumers who wish to consume whole grains but are averse to the taste, flavor and texture of whole grain flour products.
With his finger on the power button, Raj the master baker explains how the grains are feed into the central hopper to travel through the machine and be transformed into fresh flour which is then bagged and labeled for the bakers in the next room. Stone ground flour is usually coarser than commercial flour reducing the loss of nutrients due to oxygen exposure. With several studies corroborating the health risks posed by excessive consumption of processed foods, consumers are increasingly including higher quantities of whole grain and fiber into their regular diet. Using this stone ground flour, the endosperm, bran, and germ of the sprouted grains are in their natural, original proportions allowing for higher and better nutrient absorption in the body.
Shasha brand Ezekiel bread is composed of over a dozen different types of flour so the grinder has a busy job.
History of Sourdough Baking - In the Encyclopedia of Food Microbiology M.G. Gaenzle writes "The origins of bread-making are so ancient that everything said about them must be pure speculation. One of the oldest sourdough breads dates from 3700 BC and was excavated in Switzerland, but the origin of sourdough fermentation likely relates to the origin of agriculture in the Fertile Crescent several thousand years earlier... Bread production relied on the use of sourdough as a leavening agent for most of human history; the use of baker's yeast as a leavening agent dates back less than 150 years."Sourdough remained the usual form of leavening down into the European medieval times until being replaced by barm from the beer brewing process, and then later purpose-cultured yeast.
Raj prepares loaves of sourdough bread made from the nutrient rich sprouted grain flour, and then leaves them to rise in a warm room. This is one of the principle differences between artisanal bakeries and commercial breadmakers; the urban bread factories make their bleached white product in under an hour. The flour is mixed, baked, sliced and bagged in too short a time period to allow what's left of the nutrients in the pulverized wheat flour to be released into the bread. Bakers like Raj take it nice and slow and let the bacteria in the sourdough bread break down the gluten and naturally rises up into tall heathly loaves full of natural vitamins and minerals.
This is my favourite picture of Raj the breadmaker!
Today bakers in Toronto and all over Canada can buy dried BIO-Buds to add to their meals, and they can buy flour made from sprouted grains to make their baked goods.
These sprouted grains are dried and sold separately as BIO-Bud baking ingredients in the organic food store on the premises.
Always interested in how new technology improves people's lives, Fuel Ghoul was quick to accept an invitation from Markham dentist at Armadale Dentistry to watch Dr Gabriala Vidmar demonstrate a diode laser during real life dental surgery. This is a first hand account of how modern dentists now use lasers to do soft tissue surgery, and real laser teeth whitening. The future has arrived at this dental office in Markham.
Gabriala Vidmar has been practicing dentistry in Markham for many years at Armadale Dentistry which is located in building 4A in the shopping plaza complex at 7720 Markham rd. at the heart of the big box store complex that has grown up south of Hwy7, and the old Town of Markham.
Gabriala is a veteran dentist who graduated with a bachelor's degree in general dentistry in 1997. Since her graduation, she has continued to pursue extensive training and education in the field of cosmetic dentistry, root canal therapy, oral surgery and Invisalign®. Gabriala also likes new technology and hopes that someday the dental laser might replace the dentist's drill to offer quieter more comfortable treatments everywhere inside and even outside the mouth.
Ezlase products came to the attention of office administrators at Armadale Dentistry last year, because the 940 model delivers up to seven watts of laser power which most dentists believe makes the impliment more of a surgeon's tool, and not just a teeth whitening pen or gimmicky toy. Also notable is that this handheld surgical device comes with a powerful battery right inside the pen itself.. so most procedures can be done without the power supply cord attached. The battery holds a good charge, so she can work with the cordless tool all day long, and doesnt have to constantly worry about anything dangling in the patient's face. That also means she has more freedom to maneuver the ezlase dental laser during complicated operations which all adds up to faster, safer, and more efficient surgery.
The device came in a small cardboard box in which there was also included a laminate brochure which reads 'The ezlase offers the most precise control of tissue cutting for different procedures and tissue biotypes. Dentists and clinicians can choose from the widest selection of tip lengths and diameters", and under the heading 'Soft Tissue Surgery', the description continues, "The ezlase uses better bendable tips for better access to all areas, and offers single-use disposable tips for quick, convenient treatment, and improved cleanliness."
Laser tips are disposable? hmm Fuel Ghoul predicts this will be a big business someday. More research needed to investigate the possiblility of making the largest dental tips inventory warehouse in North America.
Markham Dentist readies Armadale Dentistry clinic's ezlase 940 diode laser for a demonstration.
Specialy trained and now very experienced with lasers, Dr Gabriala Vidmar is also a caring and knowledgeable dentist who devotes herself to patient care. Her vision for the clinic is to offer state-of-the-art comprehensive dental care while achieving her patients’ optimal oral health and esthetics. She wants folks to know that she has the latest high technology devices and can offer a more comfortable experience and get more done in less time
Armadale Dentistry has become a bastion of technology using digital xrays and other advanced machines. Dr Vidmar hopes the laser will someday replace the dentists' drill for all operations. Already the device is quieter and doesnt terrorize patients with loud whinny noise of an electric motor and spinning drill bit.
Its estimated that less than ten percent of Canadian dentists own and are trained to use lasers for soft-tissue surgery. The highly specialized surgery is perhaps the high art of modern dentistry.
Biolase's proprietary laser products incorporate approximately 300 patented and patent-pending technologies. The common goal of the research is to provide superior performance with less pain and faster recovery times. The company's innovative products provide cutting-edge technology at competitive prices.
BIOLASE is acquiring quite a good reputation for offering a diversified array of different dental laser systems that perform a broad range of dental procedures. Their tools are used for both cosmetic and complex surgical applications. In one article I read, the author stated that BIOLASE has sold more than 25,000 laser systems in markets all over the world, and that piece was dated Jan 2014. Other laser products they currently have in development address ophthalmology and other medical and consumer markets.
Benefits of Laser Dentistry
Lasers offer many advantages over the scapel, that cruel knife has been the prinicple cutting tool of surgeons the world. However, procedures that are performed using the new soft tissue dental lasers are less painful, lass damaging, more sterile and they heal faster. In many cases the patient's mouth, skin, gums do not require sutures (stitches) after the operation. Certain laser dentistry procedures do not require anesthesia.
This is mostly because laser dentistry minimizes bleeding and swelling during soft tissue treatments. Bacterial infections are also minimized because the high-energy beam sterilizes the area being worked on. Damage to surrounding tissue is minimized and that means wounds heal faster, and tissues can be regenerated by the body easier
Top Seven Dental Procedures for which the Ezlase 940 Diode Laser is Commonly Applied
Remove Cold Sores - Low intensity dental lasers reduce pain associated with cold sores and minimize healing time.
Treating Gum Disease - Lasers are used to remove diseased, infected, inflamed and necrosed (dead) soft tissue within the periodontal pocket.
Crown Lengthening - Dental lasers can be used to reshape gum tissue to expose healthier tooth structure. Referred to as crown lengthening, such reshaping provides a stronger foundation for the placement of restoration.
Gummy Bear Smile - Dental lasers can reshape gum tissue to expose healthy tooth structure and improve the appearance of a gummy smile.
Muscle Attachment (Frenula) - A laser frenectomy is an ideal treatment option for children who are tongue tied (restricted or tight frenulum) and babies unable to breast feed adequately due to limited tongue movement. A laser frenectomy may also help to eliminate speech impediments.
Soft Tissue Folds (Epulis) - Dental lasers may be used for the painless and suture-free removal of soft tissue folds often caused by ill-fitting dentures.
Removing Benign Tumors - Dental lasers may be used for the painless and suture-free removal of benign tumors from the gums, palate, sides of cheeks and lips.
Biopsy or lesion removal - Lasers can be used to remove a small piece of tissue (called a biopsy) so that it can be examined by specialists for cancer.
The Biolase ezlase 940 Dental Laser
In addition to it's diverse functionality, the administrators at Armadale dentistry were no doubt also influenced by an exclusive ezlase feature called ComfortPulse™ which lets dentists significantly reduce the amount of time the laser is actually cutting flesh, which works to avoid heat that can cause pain at the surgical site. This unique combination of features means that she can perform most ezlase procedures using topical anesthetic only.
The science of using laser for soft tissue dental surgery
Recent research in the field of laser wavelength absorbtion and innovations inspried by this data has positioned BIOLASE Technology as the leader in medical and dental laser systems. They used the research data to develop the ezlase 940, the first dental laser to obtain clearance at the unique 940 nm wavelength.
Biolase ezlase model 940 dental laser operates at 940 nm wavelength which research proves resonates or rather is better absorbed by hemoglobin and oxyhemoglobin than other wavelengths, so the ezlase cuts more efficiently at lower power and with less heat.
The ezlase is FDA cleared for temporary relief of minor pain. The exclusive beam-dispersing handpiece has several therapeutic applications, including providing temporary relief of minor muscle and joint pain and stiffness.
How do lasers work in dentistry?
All lasers work by delivering energy in the form of light. When used for surgical and dental procedures, the laser is most frequently used as a cutting instrumen, and less frequently as a vaporizer of tissue. When used for "curing" a filling, the laser helps to strengthen the bond between the filling and the tooth. When used in teeth whitening procedures, the laser acts as an activator and enhances the effect of tooth whitening agents.
While all diode lasers cut tissue using heat, many of them can increase tissue temperature excessively, causing patient discomfort. The ezlase keeps patients more comfortable two ways.
Using the ezlase 940 Diode Laser for Teeth Whitening
Diode Dental Laser is designed for a wide variety of procedures, including teeth whitening. Diode Laser Teeth Whitening is achieved with a proprietary photo-activated whitening gel that is activated by the selective absorption characteristics of a specific true-laser wavelength of light.
Even though its quick, it works. The Diode Laser Whitening procedure is completed in just four short sessions, that each last about thirty seconds each, and which are all performed in the course of one short visit, and the results are truly amazing. The new device has proven itself to be one of the most effective teeth whitening instruments available on the market today. The technology has already transformed the appearance of thousands of Canadians teeth, and is remarkably effective even on the worst case scenarios, ie teeth that are yellowed or gray in color, Diode Laser Teeth Whitening offers outstanding results. A full-mouth, in-office whitening can be performed in only 20 minutes, which makes it faster than any other in-office whitening system.
Consumers need to be better educated to know that most dental offices and almost all spas and salons that offer “laser teeth whitening” do not, in fact, use an actual diode laser in the procedure. The term “laser” has been rather loosely applied to every light emitting tool and the lights that most folks use are actually non-laser plasma lights. There is a significant difference in both the effectiveness and safety of these plasma lights, versus true diode laser activation.
The ezlase 940 uses new technology to provide greater patient comfort and superior control of bleeding during dental procedures. Small and ultralight, the ezlase 940 enables this Markham area dental clinic to proudly and confidently offer better dentistry services, which more proceducres done faster and more comfortably than ever before. Can your dentist say the same?
Europeans better understand that simply changing the oil in your automobile is not a complete cleanse. It's a fact that a few hundred milliliters of used oil and sludge may remain in your engine after a traditional oil change. This sludge often has the worst and heaviest contaminants that could lead to mechanical breakdowns, premature engine failure, and costly repairs.
