Alllllllrighty then!
Bought 3 grams, did three washes as follows.
Made Epsom Salts (Magnesium Sulphate) anhydrous by placing in microwave safe dish until sizzling stopped, and then some. It looked a
very clean white, and was awfully hard. Crushed that into a fine powder with my trusty mortar and pestle. I placed 10 grams of this into my 1 quart Acetone container from Home Despot.
Much shaking was followed. After numerous periods of shaking, and about 3 hours of settling, I drew some of the top acetone off to analyze. Evaporated very quickly, with no residue. Yay! Moving on.
I took a 50mL screw top test tube, and placed 3 grams cocaine (finely crushed with a spoon) into the test tube. 30mLs of anhydrous acetone followed. I screwed the cap on, and shook the fuck out of that beast.
I wish I had a centrifuge.
Let settle for a bit, and poured off as much acetone only as I could into a coffee filter/funnel into a beaker. I added 25mL acetone to the test tube, and repeated the shake. I poured this off again, and repeated one more time. I finagled as much of the gooey white coke into the filter as I could (that stuff likes to stick to the bottom!)
I put about 10mL acetone through the filter once more. (doesn't hurt to be thorough...)
Let most of the acetone filter through, and selected a shallow glass microwavable plate to use next.
I carefully ripped the filter down the side, and scraped the precious sludge onto the plate. I spread this as thin as I could to increase surface area and speed evap. time, and when it had dried a bit more, I placed this into the microwave. (Note: it is very dangerous to place anything that has solvent in it in a microwave. I felt safe in the amount I was using, and I previously moved all solvent away from the microwave. This was also done in a well ventilated room.)
I microwaved for 3:30 minutes, checked on it, chopped it up, and I don't know about you guys, but my sense of taste is WAY better than my sense of smell. So after tasting that unique sweetness, (acetone left in there!) I popped it back into the microwave. I continued microwaving, chopping, and tasting the tiniest amounts until there was absolutely no discernable taste. (except coke of course) After that I nuked it for an extra 2 minutes just to be sure.
By this time, the coke was about as fluffy and white as I could ever have imagined. I managed to end with about 2.1 grams of final beautiful product. I'm sitting here right now with some leftovers and a fucking numb as hell mouth.
Good stuff LeJunk, Thanks!
