Yes, you can cut them in half. Many people do. I've heard some people cut them in thirds, but it gets a little tough to judge color when they're that small. I just use them as is, at $0.20 a pop it's not enough for me to worry about. I usually use two per batch, the $0.20/batch savings isn't enough for me justify more work.Although, I wonder if the ColorpHast strips are one of those things that we could get a group buy together for. I bet they're uber-cheap in bulk.

Interesting question...

No, chalk is calcium carbonate.

Thanks. I got thrown off by the "chalk board" common name, when it is in fact gypsum.Carry on.And yes, we add salts to our water. Calcium Sulfate and Calcium Chloride.MolBasser

I was sort of right.

Blackboard chalk is a substance used for drawing on rough surfaces, as it readily crumbles leaving particles that stick loosely to these surfaces. Although traditionally composed of natural chalk, modern blackboard chalk is generally made from the mineral gypsum (calcium sulfate), often supplied in sticks of compressed powder about 10 cm long.

Which means you were also sort of wrong! Just kidding - didn't know chalkboard chalk was gypsum. That's not a mistake you want to make when adjusting mash chemistry!
