It could be compared with ice, which, too is water in crystaline form, but there is this an important difference; ice will melt, or change to water, when it is exposed to a to temperature above 32 F. Water of crystalization, in gypsum, does not change until it is subjected to heat above 212 F but at that temperature the water of crystalization changes form and becomes water vapor and is driven off from the gypsum just as steam is driven off from water at 212 F.
