BECAUSE IF WE HEAT GYPSUM MORE THAN FIXED TEMPERATURE IT WILL BECOME SO HARD AND THAT IS NOT PLASTER OF PARIS SO THATSWHY GYPSUM IS HEATED IN SUITABLE TEMPERATURE TO MAKE IT POP.

Kindly note: This question is also asked saying 373K (in kelvin) which is also approximately the same value of 100 degree C.
Yes. Gypsum should not be heated in more than 100 degree Celsius. If heated, the product formed will be anhydrous powder of Calcium sulphate(CaSO4) instead of Plaster of Paris (or) Calcium sulphate hemihydrate (CaSO4. 1/2 H2O).
Hope it helps:)
