| At a red heat the litharge and borate of lead are fused, and cause the adhesion of the platinum to the softened glass. |
| Another way is to take two unciae of ore, a semi-uncia of litharge, two drachmae of Venetian glass and a semi-uncia of saltpetre. |
| Red lead is produced by heating litharge at a carefully controlled temperature, lower than that used for the manufacture of litharge. |
| Fluxing agents include lead oxide or litharge which is used as a collector of precious metals. |
| The largest single use of litharge, sometimes blended with red lead and other additives, is as a paste material for storage batteries. |
| Black oxide is a mixture of litharge and finely divided metallic lead and is primarily used in batteries. |
