When water (H 2 O) is added very carefully to dolime (CaO.MgO), under normal atmospheric conditions, a further chemical process called hydration (also called slaking) takes place and the resulting material is called half hydrated lime and is a mixture of calcium hydroxide and magnesium oxide [Ca(OH) 2. MgO].
