Gypsum is a non-metallic mineral, found in rock form. It is composed of 79.1% calcium sulphate and 20.9% water, by weight. Chemists call it Hydrous Calcium Sulphate, and as there is one molecule of calcium sulphate combined with two molecules of water. It has the chemical formula CaSO 4 2H 2 0. By volume this works out to nearly 50% water in ...
Calcination makes for perfect plaster. The rock from the homogeniser is ground down even further before it goes through what's called the calcination process. Here, any water from the rock is removed in a low temperature kettle to create the first resemblance of plaster powder. This then travels through the mill, where the particle size of ...
