Lead Carbonate

Alternate Names: White lead

Oxide Analysis Formula
PbO 86.51% 1.00
CO2 13.49%n/a
Oxide Weight 223.20
Formula Weight 258.00


Lead carbonate is made industrially from lead(II) acetate and carbon dioxide and occurs naturally as the mineral Cerussite.

Lead carbonate is an extremely fine powder which can easily become airborne creating a major risk of inhalation. It decomposes at 400C and a product of the decomposition is the oxide PbO. It is much more likely to vaporize in a reduction firing atmosphere (which can easily happen in electric kilns).

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.
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.
