    Preindustrial Lime Kilns Historic England

    This IHA provides an introduction to preindustrial lime kilns. A lime kiln was a structure used to manufacture lime calcium oxide by burning calcium carbonate at temperatures above 900C. The calcium carbonate burned or calcined was commonly limestone or chalk, but occasionally other materials such as oyster or egg shells were used.
