ok so the question about the cookie you first posted. sounds like it honeycombed up because you whipped it or heated it too much during the purge. never whip. it makes the butane bind with the oil. and you can never get it out after that unless you redissolve in solvent.
your gonna want to get a infrared thermometer to monitor the temps of your oil accurately.
if you want to make shatter(the amberglass, goldglass, see thru glassy stuff) you want to purge "low and slow". once you have your un-agitated oil in your chamber you vac purge with no heat for at least a few hours, then slowly turn up the heat. I usually go from 80 - 100-105 over probly a 6 - 8 hour period and then let the oil purge at 99-105 (depending on strain) for at least another 12 hours.
making honeycomb is the same as shatter but instead of not letting the oil get too hot, you get it up to 115-125, and keep it there until the entire slab has waxed over. wax is generally less desirable.
