How calcium and carbonate helps in shell formation

Basically, chemistry in the deep ocean stabilizes the concentrations of calcium and carbonate in the seawater, which is why the upper part of the ocean is saturated with calcium carbonate and perfect for shell-building to begin with. Except we forgot to take into account the chemistry of another key part of the ocean-- the atmosphere.

Calcium Carbonate an overview ScienceDirect Topics

Calcium carbonate is abundantly available in nature as limestone, chalkboard, or marble and CaCO 3 fillers from these minerals can be produced at very low cost. Three forms of CaCO 3 fillers are used; arranged in the order of purity, they are dry processed, beneficiated, and precipitated. Calcium carbonate is considered a soft, nonabrasive filler.
