Description

Chrome green at 100x (Visible light on left / UV light on right)
Chrome green at 500x

A term used for many different green compounds containing Chromium. As early as 1809, chromium oxide, or chromia, was used as an enamel in porcelain factories. It was later sold as a stable, transparent green pigment in 1838 by Pannetier and Binet in Paris. However, the term also became used for Viridian and later for a pigment mixture prepared with chrome yellow (Lead chromate) and Prussian blue. Originally chrome green was used in artists paints, inks and glasses, but its used decreased to just house paints and industrial products.
