Triangle calcite crystal cluster from Turkey.\nCalcite is a mineral name and the chemical structure of this mineral, called carbonate rocks, is CaCO3. It is found in crystal form in various shapes (crystallizes as rhomboid, scalenoeder) and has a glassy, ​​colorless and transparent structure. It is easily ground and a white powder is obtained. Its hardness is 3 on Moh's scale and its density is 2.6-2.7.
