Glow in the dark powder, Strontium aluminate glow powder

Kosmic Super RED glow in the dark powder. (ZINC) This red glow in the dark powder is made from zinc sulfide. Unlike the strontium aluminate base colors these do not glow as long. Like all zinc sulfide based powders it does have a unpleasant odor. When mixed with a medium and painted this is usually not an issue. You cant beat this color though.
