Thanks mate. Thats basically what SWIM did. The gunk left in jar before freezing was left on bottom, and the shellitle/dmt solution transferred to seperate jar in which it was to be frozen. A small amount of shellite was swirled through the wash jar to pick up any remaining traces of dmt and added to the main jar for freezing. SWIM's question is directed at after freezing, as far as gunk in the bottom. It appeared that there was crystals on the bottom of the jar after freezing and SWIM wasn't sure whether these were in fact crystals, or just more gunk carried through? Thanks for your comments endlessness...Very helpful:d
