GLOW IN THE DARK POWDER
The effect of glow in the dark powder varies depending on a variety of circumstances, including product chemistry, the light source used to charge it, and quantity of powder used. The longer it goes without being charged by a light source, the more the glow will fade. Remember, too, that the glowing effect can fade over time. Although some glow in the dark products are said to last as much as 20-30 years.
GLOW IN THE DARK POWDER
Mixing glow in the dark powder into your resin is a lot like tinting it with dye. You'll want to add the powder after you've thoroughly combined both of the resin components so that you're able to see that all the parts have mixed together. In order to do so correctly, always pay attention to the instructions on our product bottles.
Keep in mind that glow in the dark powder works as a result of light reaching it and reacting with it. Due to that, the more translucent your epoxy, the better. Therefore, if you intend to add color to your work, the more opaque, the less light that will reach. It's not impossible for tinted epoxy to contain effective glow in the dark qualities, just something to be aware of!
Once you've got the basics down, it's still a good idea to start small. But don't worry, with practice, you could someday elevate your technique. Some people have even used these skills to design unreal eccentric living spaces with glow in the dark epoxy floors and countertops.
Due to supply shortages, this glow pigment is slightly different than our previous one. We have tested it and found it to perform fabulously! The powder is lighter in color with less green and can be mixed with other colors very well.
By the way, similar to the phosphoresecence of glow-in-the-dark is another quality of light that we encounter in polymer clay called fluorescence. Some colors/brands of polymer clay have added fluorescent dyes that make the colors appear more bright. Learn more in my article about Optical Brighteners in Polymer Clay. You can use these fluorescent qualities in your polymer clay designs, too. Learn more and see examples in my article about UV Reactive Designs in Polymer Clay.
I found that mixing the powder into the clay was quite drying on my hands and it did sting on a cut, so you might prefer to wear gloves. (Though I never saw anything about GITD powder being toxic.) I found that the purple glow pigment was very faint and while it did glow, the others were so much brighter. I even added twice the amount of powder, and it still was pretty faint compared to the others.
Thanks so much for the research!Here are some of the tiny lanterns I made. -public/I made my own GITD clay using the Smooth-on product Glow Worm Green.The proportions of powder to clay are about the same as the product you used.Thanks again,Victoria
Like you I love the glow in the dark clays ? and was excited when I found them, I have used them in many projects but found that if I mixed the different brands of clay together I was able to get the strength needed from the clay, but was never happy with how long the glow lasted.I am so going to buy some of the powders and give them a go ? and revisits some of the projects that I already done and hope that they work better this time around ?Thank you for taking the time to resurch this for us all ? your a gem ?Have a great week ?Kind Regards Dawsie
You can use this powder with epoxy resin, UV resin, polymer clay, nail art, painting and more.Just a little will be sufficient when using with resin. Too much of these will make the resin sticky.
NOTE: Purchasers should always test and evaluate how any epoxy colorant looks prior to a final mixing for a project. It is up to you to determine suitability of such products for their particular use. The powdered colorant shown on the listing, website, brochure or any marketing materials may not be exact due to limited computer monitor/printing processes. Each individual views color differently. Please contact us if you have any questions about the resin color before you purchase.
Phosphorescence is a type of photoluminescence related to fluorescence. When exposed to light (radiation) of a shorter wavelength, a phosphorescent substance will glow, absorbing the light and reemitting it at a longer wavelength. Unlike fluorescence, a phosphorescent material does not immediately reemit the radiation it absorbs. Instead, a phosphorescent material absorbs some of the radiation energy and reemits it for a much longer time after the radiation source is removed.
In a general sense, there is no distinct boundary between the emission times of fluorescence and phosphorescence (i.e.: if a substance glows under a black light it is generally considered fluorescent, and if it glows in the dark it is often simply called phosphorescent). In a modern, scientific sense, the phenomena can usually be classified by the three different mechanisms that produce the light, and the typical timescales during which those mechanisms emit light. Whereas fluorescent materials stop emitting light within nanoseconds (billionths of a second) after the excitation radiation is removed, phosphorescent materials may continue to emit an afterglow ranging from a few microseconds to many hours after the excitation is removed.
Everyday examples of phosphorescent materials are the glow-in-the-dark toys, stickers, paint and clock dials that glow after being charged with a bright light such as in any normal reading or room light. Typically, the glow slowly fades out, sometimes within a few minutes or up to a few hours in a dark room.
The term phosphor had been used since the Middle Ages to describe minerals that glowed in the dark. One of the most famous, but not the first, was Bolognian phosphor. Around 1604, Vincenzo Casciarolo discovered a "lapis solaris" near Bologna, Italy. Once heated in an oxygen-rich furnace, it thereafter absorbed sunlight and glowed in the dark. In 1677, Hennig Brand isolated a new element that glowed due to a chemiluminescent reaction when exposed to air, and named it "phosphorus".
In contrast, the term luminescence (from the Latin lumen for "light"), was coined by Eilhardt Wiedemann in 1888 as a term to refer to "light without heat", while "fluorescence" by Sir George Stokes in 1852, when he noticed that, when exposing a solution of quinine sulfate to light refracted through a prism, the solution glowed when exposed to the mysterious invisible-light (now known to be UV light) beyond the violet end of the spectrum. Stokes formed the term from a combination of fluorspar and opalescence (preferring to use a mineral instead of a solution), albeit it was later discovered that fluorspar glows due to phosphorescence.
There was much confusion between the meanings of these terms throughout the late nineteenth to mid-twentieth centuries. Whereas the term "fluorescence" tended to refer to luminescence that ceased immediately (by human-eye standards) when removed from excitation, "phosphorescence" referred to virtually any substance that glowed for appreciable periods in darkness, sometimes to include even chemiluminescence (which occasionally produced substantial amounts of heat). Only after the 1950s and 1960s did advances in quantum electronics, spectroscopy, and lasers provide a measure to distinguish between the various processes that emit the light, although in common speech the distinctions are still often rather vague.
In simple terms, phosphorescence is a process in which energy absorbed by a substance is released relatively slowly in the form of light. This is in some cases the mechanism used for glow-in-the-dark materials which are "charged" by exposure to light. Unlike the relatively swift reactions in fluorescence, such as those seen in laser mediums like the common ruby, phosphorescent materials "store" absorbed energy for a longer time, as the processes required to reemit energy occur less often. However, timescale is still only a general distinction, as there are slow-emitting fluorescent materials, for example uranyl salts, and, likewise, some phosphorescent materials like zinc sulfide (in violet) are very fast. Scientifically, the phenomena are classified by the different mechanisms that produce the light, as materials that phosphoresce may be suitable for some purposes such as lighting, but may be completely unsuitable for others that require fluorescence, like lasers. Further blurring the lines, a substance may emit light by one, two, or all three mechanisms depending on the material and excitation conditions.
When the stored energy becomes locked in by the spin of the atomic electrons, a triplet state can occur, slowing the emission of light, sometimes by several orders of magnitude. Because the atoms usually begin in a singlet state of spin, favoring fluorescence, these types of phosphors typically produce both types of emission during illumination, and then a dimmer afterglow of strictly phosphorescent light typically lasting less than a second after the illumination is switched off.
The release of energy in this way is a completely random process, governed mostly by the average temperature of the material versus the "depth" of the trap, or how many electron-volts it exerts. A trap that has a depth of 2.0 electron-volts would require a great amount of thermal energy (very high temperatures) to overcome the attraction, while at a depth of 0.1 electron-volts very little heat (very cold temperatures) are needed for the trap to even hold an electron. Higher temperatures may cause the faster release of energy, resulting in a brighter yet short-lived emission, while lower temperatures may produce dimmer but longer-lasting glows. Temperatures that are too hot or cold, depending on the substance, may not allow the accumulation or release of energy at all. The ideal depth of trap for persistent phosphorescence at room temperature is typically between 0.6 and 0.7 electron-volts. If the phosphorescent quantum yield is high, that is, if the substance has a large number of traps of the correct depth, these substances will release significant amounts of light over long time scales, creating so-called "glow in the dark" materials. 041b061a72
