Luminous Glow-In-The-Dark Pigment Powder, Half-Oz Bag

Assortment 1: All colors, no granulars. Yellow, Green, Aqua, Blue, Purple.
Assortment 2: All colors. Yellow, Green, Granular Green, Aqua, Granular Aqua, Blue, Purple.

You will receive half an ounce (about 15 grams) of glow-in-the-dark, or phosphorescent, pigment powder. It can be used to make paint with various mediums, and all kinds of arts or crafts projects. Assortments contain multiple 1/2oz bags, so 2.5oz-3.5oz total.

It is also used industrially for safety "EXIT" signs, as seen in many stores today. The powders are made of various rare-earth doped compounds, such as strontium aluminate and calcium aluminate, they are all guaranteed high-quality and pure from my suppliers.

They are all about as bright when fully charged, but some die down faster than others, also due to your eyes' sensitivity to various colors, green will always appear brightest, even if it isn't technically making as much light. Sadly, this means the purple and red will almost always look dimmer, even though they're emitting the same amounts of light.

The "Granular" powders are a rare variant were the particles are up to 1/16th of an inch, and because of these larger crystals, their glow time and brightness are much higher than regular powders used in paints, however since the particles are so large, they will not work as well in most paint formulations.

FAQs:

Q:Is this powder re-chargeable?

A: yes, this powder is "charged" with any source of light (sunlight works great) and will glow for 2-24 hours afterwards, depending on the color and charge time. Once they stop glowing, they can always be re-charged, and do it all over again. These powders are rated not to get any dimmer or shorter-lasting for 15 years!

Q: Can I use this to make paint or nail polish?

A: Yes, you can! Unfortunately it is a little difficult, because this powder is fairly heavy, like sand, so you will either need to stir the paint before every use, or use thickeners. I've had best luck with acrylic mediums, preferably as clear as possible, and best results when painted onto a white background.

Q: How fine is the powder?

A: It's very fine, (15-45 um, 300+ mesh) probably finer than sugar, but not as fine as flour. The large-particle powders can be as big as 1/16th of an inch, and are not good for use in paints, but you can sprinkle them into craft projects for amazing star-like effects, and they glow longer and brighter!

Q: Is the powder safe?

A: Yes, the chemical compounds are completely non-toxic (and non-radioactive, unlike the 1930's glow paints!), it's about as dangerous as beach sand, meaning you should still avoid eating any (or giving it to any small hands that might eat it), but don't worry if a little spills.
