Mosaic gold

Mosaic gold, or stannic sulphide, SnS2, is obtained as a yellow scaly crystalline powder, and used as a pigment in bronzing and gilding wood and metal work. It was called by the alchemists aurum musivum, or aurum mosaicum. It is also called bronze powder.^[1]

Alchemists prepared this by combining mercury, tin, sal armonaic, and flowers of sulphur, grinding, mixing, then setting them for three hours in a sand heat. The dirty sublimate being taken off, aurum mosaicum was found at the bottom of the matrass. It was recommended in most chronical and nervous cases, and particularly convulsions of children. ^{^}
