Litharge

Alternate Names: Lead Oxide, Lead(II) oxide, Yellow lead oxide

Oxide Analysis Formula
PbO 100.00% 1.00
Oxide Weight 223.20
Formula Weight 223.20

Notes

A natural mineral form of pure lead oxide. This is not the same as white lead (this is yellow or orange), although people have commonly used the term litharge to refer to white lead (or lead carbonate).

Typecodes Flux Source
Materials that source Na2O, K2O, Li2O, CaO, MgO and other fluxes but are not feldspars or frits. Remember that materials can be flux sources but also perform many other roles. For example, talc is a flux in high temperature glazes, but a matting agent in low temperatures ones. It can also be a flux, a filler and an expansion increaser in bodies.
Typecodes Generic Material
Generic materials are those with no brand name. Normally they are theoretical, the chemistry portrays what a specimen would be if it had no contamination. Generic materials are helpful in educational situations where students need to study material theory (later they graduate to dealing with real world materials). They are also helpful where the chemistry of an actual material is not known. Often the accuracy of calculations is sufficient using generic materials.
