Limestone

In the most basic terms limestone is made up of three elements calcium carbon and oxygen in the form of calcite a crystalline form of calcium carbonate When heat is applied limestone releases carbon dioxide and transforms into burnt lime which is calcium and oxygen in the form of calcium oxide Burnt lime is very reactive and will return to calcium carbonate if it comes into contact with carbon dioxide Get price
