Howdy... Anyone know where I can get some calcium carbonate (chalk) in a hurry? I have a heap of blackboard chalk here, and I'm about to brew, and was intending on using it.
After an incredibly small amount of thought, I figured it would contain some kind of binding agent which is no good. Upon further reading, I find out that blackboard chalk is rarely made of CaCO3 anymore.... do they sell CaCO3 powder at any normal shops I could zap down and get some on a sunday arvo while my sparge water is heating?
