Phosphorescent pigments are divided into phosphorescent and fluorescent. Phosphorescent pigments contain phosphorus and have brighter, glowing colors, while fluorescent pigments emit light and glow in the dark. This range of powders from VAN d'EYCK consists of 11 phosphorescent powders with unique shimmering shades, suitable for mixing with any medium. They are used from painting in liquid glass for hobbyists to mixing with linseed oil to create oil paint or watercolor medium for watercolors. They are pure, high-quality fine-grained pigments that dissolve immediately without much effort in mixing.
