Lime is a calciumcontaining inorganic mineral composed primarily of oxides, and hydroxide, usually calcium oxide and or calcium is also the name for calcium oxide which occurs as a product of coalseam fires and in altered limestone xenoliths in volcanic ejecta. The word lime originates with its earliest use as building mortar and has the sense of sticking or adhering.
