WebbA very slow (taking days to weeks) recrystallization of meth or cocaine should yield essentially 99.999% pure, centimeter-sized crystals, but most people aren't willing to wait that long. Not to mention that requires more precise temperature control than you can get with a common oven. Might be doable with a common sous vide cooker though. WebbThere are many videos on 2 solvent recrystallization. I am not sure the hassle of using two solvents is worth it in the case of meth, though, as methanol and slow cooling (in a sealed erlenmeyer) with a 2 hours stay in the freezer usually does the trick.
