Product Application of Lead Monoxide CAS#1317-36-8
Lead monoxide is used in ointments and plasters, and in the preparation of lead subacetate solutions. It serves as a glazing agent for pottery, a glass flux for painting on porcelain and glass, and in leaded glass and varnishes. Combined with glycerol, it acts as a metal cement and is employed to produce iridescent effects on brass and bronze. It is also used for coloring sulfur-containing materials such as hair, nails, wool, and horn, as well as in the manufacture of artificial tortoise shell and horn. Additional applications include pigments for rubber, production of boiled linseed oil, and in the assay of gold and silver ores.
