Chalk Basics
Chalk is a soft, white, porous sedimentary rock, a form of limestone composed of the mineral calcite. Calcite is calcium carbonate or CaCO3. It forms under relatively deep marine conditions from the gradual accumulation of minute calcite plates shed from micro-organisms called coccolithophores. It is common to find chert or flint nodules embedded in chalk. Chalk can also refer to other compounds including magnesium silicate and calcium sulfate.
Chalk is used to make quicklime and slaked lime, mainly used as lime mortar in buildings. The traditional uses of chalk have in some cases been replaced by other substances, although the word "chalk" is often still applied to the replacements.
