      I'll admit to being confused by the caution over boiling water (or aqueous solutions) in Pyrex (borosilicate) glass. A a chemistry major, I spend hours boiling aqueous solutions over open flames. Who knew I was taking my life in my hands?

Copper, tubes, benders, pumps, all of that are no problem, but I am having a devil of a time finding a pyrex coffee pot, suitable for boiling in. Everything I'm finding both in shops and online all read "DO NOT BOIL LIQUIDS IN THIS", in big scary letters. Is this just boilerplate (ha ha....puns are awesome) safety text? Or is the requirement for pyrex an absolute? I found one that says it's a stove top coffee pot, but it also says "remove from heat the minute boiling starts", so, I am unsure (due to inexperience).
