So this is the second time ive made bho, and i cant tell if the bubbles is butane trapped in it still or just air bubbles. Sorry for the crappy picture I could only use the camera on my phone. I hot water purged for about 3 hours. I stopped once i stop seeing bubbles being formed.

No, stay away from Poly chambers. Get a 2gal aluminum chamber from best value vacs on ebay, polycarbonate chambers arent really made to be heated and they're too small.
