Hey folks,
Pretty much all of the gypsum available to me from the home improvement stores here is the hemihydrate variation (CaSO4 x 0.5H2O). Before I resort to ordering the dihydrate variety from the internet, I thought I'd ask if there is any significant difference to using hemihydrate in place of dihydrate in respect to calculations that I got from Bru'n Water.
If so, what adjustments do I need to make to get the amounts of hemihydrate needed in place of dihydrate? Are any readjustements even needed? Is it safer to just order the 2H2O variety off the net?
Thanks!
