| Phosphorescent Medium is based on a unique pigment that is characterized by its ability to absorb and store natural and artificial light and then emit it as a visible light when in the dark (glow in the dark). Phosphorescent Medium will exhibit its glow quality only after receiving direct exposure to light. Mixing with or painting over most other colors will diminish the glow. However, mixing this product with the fluorescents can yield various other colors that will phosphoresce, but with a diminished glow quality. Thicker applications will yield longer glow times. Note: Phosphorescent Medium is not lightfast. |
