Precipitated Lime

Alternate Names: Precipitated Calcium Carbonate, PCC

Description: Synthetic calcium carbonate

Oxide	Analysis	Formula
CaO	56.10%	1.00
CO2	43.90%	n/a
Oxide Weight		56.10
Formula Weight		100.00

Notes

Made by heating calcium carbonate to remove the CO2 and make calcium hydroxide, adding water and purifying and then combining with the CO2 to precipitate the calcium carbonate back out leaving other impurities in the slurry. We are thus representing the chemistry as the theoretical pure CaCO₃.

Ultrafine Nano PCC is also available (particles finer than 0.1 microns).

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.
