good full ans this
Calcium sulphate with half a molecule of water per molecule of the salt (hemi-hydrate) is called plaster of paris (plaster of paris).
Preparation
plaster of paris is prepared by heating gypsum (CaSO4.2H2O) at 120°C in rotary kilns, where it gets partially dehydrated.

The temperature should be kept below 140°C otherwise further dehydration will take place and the setting property of the plaster will be partially reduced.
