Anything that glows in the dark is known as phosphorescent or photoluminescent.

Realglow photoluminescent pigment are chemicals that collect energy from light and store the light energy for some time making them glow for hours afterwards, even when the light source is turned off.

Charge these pigments in light first to make them glow in the dark. The longer they are charged, the longer they will hold glow. Our pigments can glow up to 10 hours!

As photoluminescent sand manufacturers ，all Realglow photoluminescent products are made using a high grade phosphor called strontium aluminate. This high strength strontium aluminate releases energy more slowly than some other phosphors, making some of the brightest and longest lasting glow-in-the-dark smart materials on the market.
