Calcium hydroxide, traditionally called slaked lime, is an inorganic compound with the chemical formula Ca(OH)2. It is a colorless crystal or white powder and is obtained when calcium oxide (called lime or quicklime) is mixed, or "slaked" with water. It has many names including hydrated lime, builders lime, slack lime, cal, or pickling lime. It is of low toxicity. Calcium hydroxide is used in many applications, including food preparation.

Uses
1) Niche uses
Because it is produced on a large scale, is easily handled, and is cheap, myriad niche and even large scale applications have been described. A partial listing follows:
-In life support systems as a carbon dioxide scrubber, particularly in closed-circuit diving re-breathers such as the US Navy LAR V or MK-16, where the more caustic Lithium Hydroxide is deemed too risky due to inhaled dust, combat handling, or generation of caustic "slurry" in flooding events
-An ingredient in whitewash, mortar, and plaster
-In road construction, to improve the quality of excessively plastic subgrade soils.
-To fill the root canal for the first stage of endodontic therapy (it is then replaced by rubber).
-As an additive to sea water to reduce atmospheric CO2 and mitigate the greenhouse effect.

2) Food industry
-In Chinese cuisine, for making century eggs
-Used to fortify fruit drinks such as orange juice.
-A calcium supplement in mineral fortified infant formula
-An Indian digestive called "paan" where areca nuts, calcium hydroxide and a variety of seeds are wrapped in betel leaves.
-Use as alternative ingredient to baking soda (raising agent) in papadam.

3) Native American uses
4) Afghan uses
5) Ancient Celtic use
