akcapr Posted April 23, 2005 Posted April 23, 2005 How could i make plaster of paris out of calcium sulfate (and no they arent exactly the same)? When i put calcium sulfate in water and dry its not hard at all. I heard you have to make it into gypsum or something.
H2SO4 Posted April 24, 2005 Posted April 24, 2005 Plaster of paris isnt just calcium sulfate. Its a mix of calcium sulfate, calcium carbonate, and "crystaline silica". refresh my mind, wats "silica" i know its a silicon compound though. is it just silicon dioxide?
H2SO4 Posted April 24, 2005 Posted April 24, 2005 ya, but ive just called it silicon dioxide for so long its like engrained in my brain (if thatg makes any sense).
