When Gypsum ( CaSO 4,2H 2O) is ground to a powder and heated at 150° to 165° C, three-quarters of its combined water is removed producing hemi-hydrate plaster ( CaSO 4,1/2H 2O), commonly known as the 'Plaster of Paris'. When this powder is mixed with water the resulting paste sets hard as the water recombines to produce Gypsum again.
While that would result in a healthy 1 and 1/2 inches of gypsum on one side of a row of studs, you would be hard pressed to find the fire test documentation that would support the calculation.
