Art ‘N Glow Epoxy Resin can easily be colored with our wide variety of pigment powders. We typically recommend approximately 7 grams of glow powder for each fluid ounce of resin and hardener mixture. This ratio is designed to give your resin piece the brightest and longest-lasting glow. However, there is room for experimentation if you wish to use more or less glow powder. If using Art ‘N Glow Pearl Pigments, pour small amounts of the powder until you reach the desired depth of color.
