Product Application of Lead monoxide CAS#1317-36-8
It is widely used in ointments and plasters, and for preparing lead subacetate solutions. It serves as a glazing agent for pottery, a flux for porcelain and glass painting, and a raw material for lead glass production. It is applied in varnishes, and used with glycerol to make metal cement. It can create iridescent colors on brass and bronze surfaces, and dye sulfur-containing materials such as hair, nails, wool and horn. It is used in manufacturing artificial tortoise shell and horn, as a rubber pigment, and in producing boiled linseed oil. Additionally, it is used in the assaying of gold and silver ores.
