Calcium Carbonate powder - Chalk Arts and Crafts A heavy-duty degreaserCALCIUM CARBONATE Technical Industrial Grade Calcium carbonate, commonly known as chalk or calcite is a non combustible, non toxic, odourless white powder with the formula CaCO3. It occurs naturally in the minerals aragonite, calcite, limestone and marble which makes up about 4% of the earths crust. Calcium carbonate is produced by the sedimentation of the shells of small fossilized eggs, skeletons, snails, shellfish, and coral over millions of years.
