Golden Phosphorescent Green Medium, 16 oz.

This water-based acrylic medium can be applied to various surfaces. The unique pigment absorbs and stores both natural and artificial light, resulting in glow in the dark effects. Turn off the lights or place your artwork in dark space to discover a bright, greenish glow. Create interesting effects with fine art or explore fun projects (like starry ceilings). The glow steadily diminishes as the stored light energy is released and needs to be "re-charged" with light.
