Mine comes as "flakes" -- thin plates about 1mm thick, irregularly shaped from 4 - 15 mm across. They can be snapped into smaller bits in your fingers, but grinding them would make a lot of very nasty dust. It is very hygroscopic, even worse than NaOH, and it can't be dried in the oven (it justs "melts" into solution). But you're correct that even in large flakes it dissolves more readily in methanol than NaOH does, and with greater exotherm. ------------------------ Yahoo!
