Common Misconceptions about Gypsum. Gypsum, composed of calcium sulfate dihydrate (CaSO₄·2H₂O), provides calcium and sulfur to the soil without affecting its pH. This is because the sulfate in gypsum is already in a soluble form, readily available to plants without undergoing chemical reactions that would alter the soil's acidity or ...

Applied in a plastic state (with water), it sets and hardens by chemical recombination of the gypsum with water. For an especially hard-finish plaster, the gypsum is completely dehydrated at a high temperature, and such chemicals as alkali sulfate, alum, or borax are added. Hair or fibre and lime or clay may be added to plasters during manufacture.
