About
Zinc sulfide doped with a small amount of copper or similar activator to give a glow-in-the-dark effect. The base is fairly inert, but the metal activators and dust exposure earn it a cautious yellow.

- Long-wear visual effect
Known concerns
- Activator dopants (Cu/Ag/Mn) require purity controls
