    Gypsum is a common mineral obtained from surface and underground deposits It can be a valuable source of both calcium (Ca) and sulfur (S) for plants and can benefit certain soil properties under specific conditions Production Gypsum is found in both crystal and rock formsthe factors that determine production of an ideal plaster mix , Plaster with good soaking properties will sink slowly into the water and become almost completely wetted after 3 or 4 minut Short-cuts in soaking will influence , application be developed and followed as standard procedure.

    INSOLUBLE ANHYDRITE or dead-burned gypsum is made by the dehydration of calcium sulfate dihydrate (gypsum) at high (>600°C) temperature At room temperature, insoluble anhydrite dissolves very slowly to the extent of 024 g per 100 g of water and does not absorb moisture from the airThis is due to the fact that gypsum is eternally recyclable, a major advantage when manufacturing gypsum into a commercial product Gypsum is also a rare example of closed loop recycling, ie the ability to use product waste to make the same product over and over.
