 [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 dark[citation needed].
