Lithopone is a white pigment consisting of a mixture of barium sulfate and zinc sulfide. It is used in interior paints and in some enamels.[1] It is widely used for white paint.

History[]

It was manufactured by Krebs Pigments and Chemical Company and other companies.[2] The material came in different "seals", which vary in percent of zinc sulfide. Gold seal and Bronze seals contain 40-50% zinc sulfide, offering more hiding power and strength.[3][4]

Characteristics[]

It is a valuable pigment that is brilliant white with fine texture which is advantageous vs white lead.[5] It mixed well with oils such as linseed oil or varnish, turns grey very fast in sunlight and white again in the darkPlantilla:Cn.
