Aug 03, 2010· * Limestone is made from creating Calcium Oxide (CaO) from Calcium Carbonate (CaCO3) through heat. Calcium Oxide, also known as unslaked lime or quick lime, is dangerous. It needs to be slaked with water first in order to be used in food. Slaked lime after evaporation becomes Calcium Hydroxide, a white powder.
