Calcium Carbonate (CaCO3) is a chemical compound which is most common natural forms from chalk, limestone, and marble, produced by the sedimentation of the shells of small fossilized snails, shellfish, and coral over millions of years. The Calcium Carbonate is the active ingredient in agricultural lime and is created when calcium ions in hard water react with carbonate ions to create limescale. It is medicinally used as a calcium supplement or as an antacid, but excessive consumption can be hazardous. The CaCO3 are identical in chemical terms, they differ in many other respects, including purity, whiteness, thickness and homogeneity.
