실험 절차

The calcination (or dehydration) step in the manufacture of stucco is performed by heating the land plaster, and generally can be described by the following chemical equation which shows that heating calcium sulfate dihydrate yields calcium sulfate hemihydrate (stucco) and water vapor: CaSO4.2H2O+heat#CaSO4.½H2O+1 ½H2O.
