Swims buddy told me to pass this along.
After once accidentally combining a nearly equal portion of pseudo to meth he had quite good luck with this.
For a quick and relatively easy way to separate a mixture of pseudo and meth do a recrystallization "newbee recryst" style with _only_ acetone. Don't use any alcohol.
Even when hot pseudo is only marginally soluble in acetone while meth is highly soluble.
Use two flasks of similar size. 125ml erlenmeyers are great for amounts up to around 2-3 grams.
For amouts between 1/2gram and a gram start off with 50ml acetone and add more as necessary. For amounts of 1 gram or more start with 75ml and add more as needed.
Heat the flask on a hotplate to about 80c and swirl it often so that a tornado-like swirl of undissolved powder is fizz-boiling. The majority of the psuedo won't dissolve. Once you think most of the meth has dissolved take it off heat and let the larger almost dissolved particles settle. This settling can take up to 5 minutes but usually goes quicker.
Then decant the acetone from flask #1 to flask #2 while leaving the undissolved powder on the bottom of flask #1.
Put back on the now off and cooling hot plate for the biggest slow forming crytals. Or don't put back on the hot plate for still good but more impatient crystals until it is room temp. (half hour maybe)
Seal with stopper and transfer to frige until it hits baseline fridge temp. Transfer to freezer for as long as you can bear.
Pour into unbleached coffee filter then rinse with fresh, cold dry acetone.
Bioassay for quality test.
There will not bee much pheddy left in the final recrystallized product but there will be a small amount.
Somewhere there is a thread by fudgemonkey called something like "get the phed out" that gives a technique for separating pseudo and meth using chlorinated tapwater. I think the jury's still out on the effectiveness of that technique. I'm guessing that it most likely does work if done correctly though.
