Random shower thoughts this morning: How much Chlorine is in random rocks you pick up to etch?
Lots of people have been talking about putting rocks in the Forge. And one type of rock is rock salt. But a salt is just an acid/base pair where the hydrogen in the acid is mostly supplanted by metal from the base.
