| Black oxide is a mixture of litharge and finely divided metallic lead and is primarily used in batteries. |
| 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. |
| It works with both powder and granular litharge. |
| Red lead is produced by heating litharge at a carefully controlled temperature, lower than that used for the manufacture of litharge. |
| De Abano in the fourteenth century included mercury, copper, lapis lazuli, arsenic sublimate, litharge, nux vomica, laurel berries, and hellebore in his De Remedis Venenorum. |
