What are inorganic pigments?
Inorganic pigments are usually oxides, sulfides, chromates, silicates, phosphates and carbonates of metallic elements. Because of their ability to interact with light, they most often contain some transition metals. Inorganic pigments have been sought and developed for a long time. Natural inorganic pigments have been known as early as prehistoric times. For example, drawings in the Pech-Merle caves in southern France, northern Spain and northern Africa were made from charcoal, ocher, manganese brown and clay. During the Renaissance, chromium oxides and various multi-metal oxide minerals also began to be used as pigments. Today, inorganic pigments have become very important substances in human life. They will continue to contribute to the beautification of our daily lives and habitats and to the emphasis and differentiation of objects.
