Lime Burning Lime Burning. Chalk is a form of calcium carbonate which when burnt at about 900 degrees C becomes quicklime (calcium oxide). If water is added it becomes slaked lime (calcium hydroxide). Lime putty is made by adding an excess of water to quicklime. Hydrated Lime was being made at most lime works by the 1950''s.

The common feature of early kilns was an eggcup shaped burning chamber, with an air inlet at the base (the "eye"), constructed of brick. Limestone was crushed (often by hand) to fairly uniform 20–60 mm (1– 2 1 ⁄ 2 in) lumps – fine stone was rejected. Successive domeshaped layers of limestone and wood or coal were built up in the kiln ...
