Raw Calcite Lumps

Other Details:

Calcite, which gets its name from "chalix" the Greek word for lime . CALCITE is a carbonate of lime (CaCo₃). Calcite is the primary mineral in metamorphic marble .It has a Mohs hardness of 3, a specific gravity of 2.71, and its luster is vitreous in crystallized varieties. Color is white or none, though shades of gray, red, yellow, green, blue, violet, brown, or even black can occur when the mineral is charged with impurities.

Uses:

Calcite in pulverized form finds use mostly as filler in rubber and textile goods. A considerable quantity is also used in the ceramics industry for the preparation of glazes. Super white quality of calcite in powder form (-300 mesh) is used in the manufacture of paint and distemper. Calcite is now insecticides. The transparent and clear crystals are used in the optical industry, for the manufacture of nicol prism. Principal characteristics which make calcite of special value for use in optical instruments are its very high birefringence, high degree of purity, perfect crystalline structure and transparency.
