PolyColor Glow Powders make resins pop in the dark and add a fun element to any project. The more you add to clear resins, the more vibrant the glow. Once applied and cured in clear resins, charge with natural or artifical light, dim the lights and watch it glow! Please keep in mind that when added to slower setting resins, Glow Powder may settle at the lowest point of the resin pour. Powder is sold in 15gm resealable bags.
