Lime kiln - stone or brick structure for calcining brooken limestone to make powdered quicklime for agricultural, construction and industrial uses. Limestone was broken up and fed into the top of the kiln onto a charcoal fire. After burning, the powdered lime was raked out through an opening at the front of the kiln. By the early C20 bulk production using machinery for crushing the stone and burning it in Hoffman kilns saw the demise of lime kilns (William Jones, 1996, Dictionary of Industrial Archaeology, AB Searle, 1935, Limestone and its products, R. Williams, 1990, Lime kilns and limeburning, Shire Publications).
