Question Crystal Meth

[Charlie3]

Crystal Ice, that is been diluted into water. So i know that when the water evaporates, it turns back into crystals.
The question i have is, is there a faster way to evaporate the water besides just leaving it aside to slowly take its course?

Have to rephrase this, Crystal Meth, thats been *dissolved* into water. what would be the best technique to evaporate the water without losing weight of the crystals.
Would water bath technique work?

Evaporate under vacuum, in a vacuum chamber perhaps? Or add some NaOH and do an acid-base extraction, but this would almost inevitably lead to some losses even if you are experienced. If you don`t have vacuum, just use some mild heat e.g. put it on the radiator.

aalright thanks !

Be aware that you will probably get powder form like this, you need to recrystallize it in IPA if you want crystals, although I don`t see why you would want that (no difference in effects).
