Question

what happens when during preparation of POP from gypsum temperature exceeds 100 degree celsius. is this POP formed is usable or not?

Answer 1

Temperature should be controlled very carefully. while preparing plaster of paris from gypsum heat must be controlled. because, it should not be allowed to rise above 152 degree celsius or 425 kelvins, if the whole water is lost then

anhydrous calcium sulphate is produced,whichis called dead burnt plaster. it does not have the properties of plaster of paris.

Then pop will be converted in to dead burnt plaster which is of no use
