Description

An off-white powder that occurs in nature as the minerals wurtzite and sphalerite. Zinc sulfide slowly oxidizes in moist air to form Zinc sulfate. The synthetic form was introduced as a pigment in 1852 but not widely used by itself due to gray tonalities from impurities. Zinc sulfide is mixed with Barium sulfate to form Lithopone.
