The phosphorescent pigments are divided into PHOSPHORESCENT - that is, pigments that contain phosphorus and are brighter with more vivid colors, and PHOSPHORESCENT GLITTER - which emit light and glow on their own in the dark. This is a series of powders from VAN d'EYCK, consisting of 11 phosphorescent powders with unique shimmering shades ideal for mixing with any base you desire. From dye in liquid glass for hobbyists to mixing with linseed oil to create oil paint or watercolor medium for watercolors. These are pure high-quality pigments with a very fine powder grain that dissolve immediately without much effort in mixing.
