ThePheonix,
I'll reiterate what Mr. Blonde said by saying that you should simplify your entire thought process and stick with just the correct acetone wash. Sometimes the easiest method is also the most effective.

This seems to be the case with about 90% or better with U.S. samples of street cocaine. The cocaine crystals were simply not washed properly during their original and hurried manufacturing process. Naturally, things were added to it along the way before ending up at your crib, but performing a 100% anhydrous acetone wash, followed by the crude yet extremely effective and now patented, Le Junk Vibration Seperation Technique (insert trademark symbol

), your results will be just as good as any more advanced and possibly detramental A/B extraction.......I promise. It took me years of doing all this and that, trying to make it better and better, only to return in the end to a simple little acetone wash. But you absolutely must use the smooth coated paper plate though to finally seperate the crystals from the ephedrine, caffeine, phenylpropanolamine, etc. before consuming the product once you've actually completed the acetone wash and waited out the FULL 48 hours. Once you've washed them properly, the crystals will virtually POP right out of the pile with ease on a smooth coated paper plate with gentle tapping from underneath. Skip all the ammonia, muriatic acid, etc. and just make it simple on yourself, okay?
The only major thing that could go wrong from a simple acetone wash would be that your acetone is not anhydrous. To make sure it is, never pour out of a can of acetone that's been made anhydrous. Instead, from the top, insert a glass pipette or eye dropper to extract the acetone. Once it gets to hard to extract, discard the old can of acetone and make a fresh can.
All the best, Le Junk
P.S. There are waaay to many things that could go wrong from an improperly performed A/B extraction and recrystallization. So without getting into all the what if's, why not just forget all about the A/B thingy and go with the simple acetone wash. Okay?

Good!
