I'm a fan of the "Measuring Calcium Chloride" thread, but I'm wondering what other common salts we should take similar care to measure out?
I note that Calcium Sulfate is sold by chemical suppliers as either anhydrous or dihydrate. Which do we typically get when we buy "Gypsum" from the homebrew suppliers? Is it as unstable and thirsty as Calcium Chloride?
