Dehydrate gypsum is the plaster in nature. After calcination process gypsum dehydrate transform to hemihydrate, AII anhydride (dry plaster) and AIII soluble (unstable gypsum). Hemihydrate, in other words named as stucco is the plaster calcined by losing 1,5 moles of the 2 moles of water.
Plaster of Paris is a more reliable plaster in the sense that it will not shrink or crack when solidified. Plaster of Paris is widely used in sculpture industries and medical institutions. Now, when the temperature is further increased, the rest of the water of crystallization will vanish and the compound becomes anhydrous.
If plaster of paris going to use for plasterboard plant, after calcination and milling classifying. Temperature of stucco gypsum has to be under 80 ⁰C. High temperature effected to the other additives.
