34 Calcium hydroxide is made from mined limestone, which is mostly calcium carbonate, in what is roughly a 35 two-step process (Oates, 2010). The limestone, sometimes simply referred to as mined or raw lime, is 36 heated to make calcium oxide, or quick lime. The quick lime is then hydrated with water to form slaked 37 lime, or calcium hydroxide.
