This is the same as presented above in De-contamination procedure
Re-crystallization of chili using methanol, denatured alcohol, or 91% isopropyl alc. will grow some very pretty, large crystals and will make your product more pure and much more potent. This is one procedure that is simplicity itself and always produces a major improvement with surprisingly little loss of product.
Super pure crystals, using denatured alc. and vision ware
After the chili was pulled out of the toluene (non-polar solution) using HCl and water, It was run through a filter and placed in a vision ware bowl for evaporation. The water was evaporated leaving the crude raw Crystals.
These were crushed and washed with ice cold dry(25%-cooked-epsom salts-inside-the-acetone-container/75%-acetone) acetone. Using a filter with cotton-ball-tipped and five or ten filters, use this to ensure the acetone is 100% stripped of not only the water which may have condensed, but the dessicant used inside!! The epsom salts. It should pour a clear liquid. Don't getsloppy here now ya hear?!
The washed Crystals were then dissolved in hot denatured alc. the alcohol was boiled away until the first sign of skin forming or the first sign of crystallization noted. Remove from the heat add enough alcohol to remove the skinning so no more crystallization can be seen then add 20 ml of acetone, if it turns cloudy add alcohol drop wise until it is clear again cover and place in freezer 6 hours or more( overnight is great) you will return to find crystals floating in the liquor.
Rapidly filter out the cold crystals , then wash them with a little cold alcohol to remove any gakk on the surface and in the outer crystal layer, set out to dry..
All three steps were performed without ever removing the chili from the vision ware bowl.
