Calcite

Calcium carbonate

Miscellaneous

Family: Flux Source
Region: None
Mined At: Unspecified
Raw Mineral: Yes
Generic: No

Notes

Melts at 2580C.

A purer form of calcium carbonte.

(Richard Willis)

Mineral, of the ideal form CaCO₃with a typical empirical analysis ofCaO 56%, CO₂ 44%, plus traces of Mg, Fe, Mn, Ba, Si, Pb, Zn, Se, and Sr. Also, there are frequently found deposits with high contents (10-20%) specifically of Mn or Pb or Sr or etceteras.
Hardness: 3 Density: 2.6-2.8 Soluble in acids
Hydrothermal. Sedimentary. Common cement in the forming of rocks. In one form or another, present in virtually all clays and glazes of ceramics, as it is the principal source for obtaining CaO. Crete, marble, lime, and chalk are natural instances of calcite.
Commonly used by stone-age potters as grog, or grit, to open clay in preparation for the direct flame, rapid firing of open (pre kiln) firings — referred to as “calcite-grogged” or “calcite-gritted wares” by archaeologists.
