An introduction to pre-industrial lime kilns. A lime kiln was a structure used to manufacture lime (calcium oxide) by burning calcium carbonate at temperatures above 900°C. The calcium carbonate burned (or 'calcined') was commonly limestone or chalk, but occasionally other materials such as oyster or egg shells were used.
