Calcium oxide (CaO), commonly known as burnt lime, iron oxide.

calcium carbonate. Calcination of limestone is one of the first chemical reactions discovered by man and was known in prehistory.

Up until the 20th century, quicklime was used as a disinfectant, usually in a 10% solution called milk of lime. However, it had the disadvantage of decomposing rapidly on exposure to air and moisture, and the burnt lime had to be fresh and unslaked.[2]
