Anotations

Scope note:

A synthetic permanent green pigment composed of hydrated chromium oxide with characteristic deep green, transparent particles that are unaffected by light and chemicals. Processes for making the pigment were developed in 1838 by Pannetier in Paris and Guignet in 1859. It has been used as a pigment in all types of binding media, and as a colorant in concrete mixtures, rubber, inks, and automotive paints.
