- Litharge abstract "Litharge is one of the natural mineral forms of lead(II) oxide, PbO. Litharge is a secondary mineral which forms from the oxidation of galena ores. It forms as coatings and encrustations with internal tetragonal crystal structure. It is dimorphous with the orthorhombic form massicot. It forms soft (Mohs hardness of 2), red, greasy-appearing crusts with a very high specific gravity of 9.14–9.35. PbO may be prepared by heating lead metal in air at approx. 600°C (lead melts at only 300°C). At this temperature it is also the end product of oxidation of other lead oxides in air. This is often done with a set of bellows pumping air over molten lead and causing the oxidized product to slip/ fall off the top into a receptacle where it quickly solidifies in minute scales.PbO2 –(293 °C)→ Pb12O19 –(351 °C)→ Pb12O17 –(375 °C)→ Pb3O4 –(605 °C)→ PbO It was first described as a mineral in 1917 for an occurrence in San Bernardino County, California.".
