Gypsum processing and use Humanitarian Library

Gypsum can be processed relatively simply with basic equipment and techniques as well as on a large and industrialized scale as is done in some countries such as the United Kingdom. It is made from deposits of gypsum rock or sand. Raw gypsum is heated to drive off a portion of the chemically combined water. The resulting gypsum plaster, when re-
