The primary ingredient in most classroom chalk is calcium carbonate, which is a form of limestone. Limestone is derived from the decomposition of plankton skeletons. Pastel or sidewalk chalks, on the other hand, use a base of calcium sulfate, which is derived from gypsum. Gypsum forms from the deposition of ocean brine.The silica replaces the original Chalk carbonate grain by grain. The carbonate has to be dissolved with silica precipitated in its place.
