hey everyone. had a quick question about bho i hope someone can answer for me. i just did a run and put the pyrex in another one filled with hot water to evaporate the butane and now its out of the water. oldskoolgrower said in his isomerized frozen hash oil crystals that you can put it in the oven at 220 for 15-20 min and then freeze it to potentiate the thc. however, he did it with iso alcohol and i did it with butane so i'm not sure the point it would be safe to put the pyrex in the oven. does anyone have any ideas? there are some bubbles in my dish but it looks like most of the butane has evaporated. would this be safe??
