this thread confuses me a little, I know it is about ISO hash, but it is very old. In fact BHO is the preferred method of making hash oil, for at least 2 years, now.
butane extraction is much safer and better product then ISO hash any day. Much more pure when done correctly as well. I use a Okeif extractor, and a butane that is refined at least 4 times.
It is important to not use heat of a open flam, and also to be out side or in a well ventilated area. here are some links and vids, to use.
Also personally I really like iceolator hash, better, the taste the high everything.
Also it is not difficult to smoke oil, they have special bowls, domes, and bells you can use with your glass on glass bong. but you really don need any of these. I use a clean bong, and a torch, like a brulee torch, or even a cigarette torch, that can be bought at the corner store.
I use about 5-8 new clean screens, and just lay them flat on the bowl, so you get a plate of screens or a flat surface on your bong bowl, blob a dab of oil on top of your screens, it is easy use your torch to keep things clean, then hit it with the torch, inhale quickly, and there you go you are taking, BHO bong hits. their are also special bowls know as oil domes, oil bells, and extract bowls, that you can buy just for smoking PURE
Oh and the oil smokers I know, always whip it, for essayer handling storing, and more PURE smoke. look up whipping hash oil if you dont know what whipping your oil is all about. I hope this helps someone, cause this thread was a long read, and I still am confused
oh I don't make to much bho, it is for growers or the rich, but I did make some recently and it was very goo, and really does take only minutes to cure and smoke.
