Making Lime

Quicklime. When a calcium limestone or chalk rock, that comprises mainly of calcium carbonate (CaCO 3), is heated in a kiln, it changes by a process called calcination into quicklime also known as 'burnt lime' and chemically is mainly calcium oxide (CaO), and the calcination process releases a gas from the rock which is carbon dioxide (CO 2)..
