Understanding gypsum in 3 diagrams

Normally, calcium sulphate dihydrate (CaSO 4 •2H 2 O) is used as a raw material and a subhydrate such as hemihydrate (CaSO 4 •0.5H 2 O) or anhydrite (CaSO 4) is produced. The subhydrate is the binding material, which reacts with water back to form gypsum. There are three main diagrams that can help us understand this cycle in detail.
