Pigments can be classified as either natural or synthetic. Natural pigments are taken from the earth or plant sources and include colorants such as metal oxides or carbon black, or various clays, calcium carbonate, mica, silicas, and talcs. Synthetics include a host of colorants created in the lab as well as engineered molecules, calcined clays, blanc fixe, precipitated calcium carbonate, and synthetic pyrogenic silicas. The pigments and dyes that are used as colorants are classified by chemical type using the Color Index system, which is commercially significant.
