It is found with the other form, massicot, as dull or greasy, very heavy, soft, red crusts in the oxidized zone of lead deposits, as at Cucamonga Peak and Fort Tejon, Calif., U.S., and near Hailey, Idaho, U.S. For mineralogic properties, see oxide mineral (table). Synthetic lead(II) oxide … The kind of lead in lead glass is normally PbO, and PbO is used extensively in making glass. Depending on the glass, the benefit of using PbO in glass can be one or more of increasing the refractive index of the glass, decreasing the viscosity of the glass, increasing the electrical resistivity of the glass, and increasing the ability of the glass to absorb X-rays. Adding PbO to industrial ceramics (as well as glass) makes the materials more magnetically and electrically inert (by raisi… WebAssay Litharge – Assay Litharge is a unique type of lead oxide used in the analysis precious metals.
