This IHA provides 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.
A lime kiln is a large, industrial furnace, and is typically either a rotating horizontal (or rotary) kiln, or an upright vertical kiln. The rotary kiln is the most common type of kiln found in the U.S. These kilns use fossil fuels with high heat content. To convert limestone to lime,
