Inorganic Pigments

Back to Pigments

This category includes the same pigments that prehistoric humans used to paint the cave walls of Grotte Chauvet. Called “inorganic” because they include minerals such as salts, complex salts, oxides, and other non-carbon-based elements. The insoluble compounds called inorganic pigments are divided into subgroups: Earth or Natural Mineral, Processed Natural Mineral, and Manufactured Mineral. These pigments can be transparent to opaque.
