Calcium carbonate is a chemical compound containing Ca 2+ and CO 32- ions. It is an odorless, water-insoluble, white colored crystal that can be most commonly found in nature. It can be found in any part of the world, and Calcium carbonate is naturally present in egg shells, limestone, marble, seashells, and coral.

Mohs hardness will scratch or abrade a material with a lower number. Calcium carbonate is a soft mineral with a Mohs of 3. Since ground calcium carbonate is a naturally mined material, impurities exist in all ore bodies. Almost all contain some dolomite (CaMg(CO 3) 2) with a Mohs of 4, while others contain mica (Mohs 3) or graphite (Mohs 1-2).
