WebLead(II) oxide, also called lead monoxide, is the inorganic compound with the molecular formula Pb O.PbO occurs in two polymorphs: litharge having a tetragonal crystal structure, and massicot having an orthorhombic crystal structure.Modern applications for PbO are mostly in lead-based industrial glass and industrial ceramics, including computer … Web—Glycerin was discovered, in 1779, by Scheele in the saponification products of olive oil by means of litharge, and later recognized by him as a common constituent of other oils and fats, and therefore named the "sweet principle of fats." Chevreul gave it the name glycerin, and cleared up the nature of its combination in the fats.
