The hydration of calcium sulphate hemihydrate to produce calcium sulphate dihydrate (gypsum plaster) has been the subject of several kinetic models, two of the most notable of which were proposed in a series of conflicting papers by Ridge and Schiller. Evidence was put forward in support of both the

Hand has used Avrami's equation to generate 'theoretical hydration curves' for calcium sulphate hemihydrate, and then has used 'data' derived from them to test equations due to Ridge (1,2) and Schiller (3). But Avrami's equation has no established validity in the field and is, in fact, irrelevant. T
