Reusing Plaster of Paris? Answered
...or simply plaster, is a type of building material based on calcium sulfate hemihydrate... It is created by heating gypsum to about 150Â°C.
...When the dry plaster powder is mixed with water, it re-forms into gypsum...
So...if I heated the gypsum to +302F (150C), it would turn back into plaster of paris, to be reused agian? Of course you would need to powder the used plaster (gypsum), but would it work?
