I've been trying an extraction from acacia obtusifolia, an A/B extraction, and I've goten to watching the crystals fall to the bottom of the container.

HOWEVER, when I tried to capture them(pour them off, or even filter them through a coffee filter) they just "disappear". I've heard that the spice has a low boiling point... but how long does it take to get good ammounts of crystals? taken, Its been less than 24 hours from putting it in the freezer, even still.... how long does it take to drop out of shellite? and is it a pain to keep in a crystal state?
