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…

It helps to decompose silica to form fusible lead silicate. PbO + SiO2 = PbSiO3 It supplies the lead to produce the lead button that collects the gold and silver. PbO: 2PbO + C (flour) = 2Pb + CO2. It also dissolves difficult-to-fuse metal oxides for example Copper. dr kucinski morris il
