What is Resin8 colour powder? An inorganic flat powder made from ultramarine or iron oxide. Iron oxide is a chemical compound made of iron and oxygen and is widely used for colouring. Ultramarine is made from powdered, fired clay. These powders are insoluble in water but mix well in oils and resins.
Does it matter if it's cosmetic grade if you're using it in epoxy resin? No, but cosmetic grade means that the colour powder is of the highest purity and has been refined to super-high standards.
