When making BHO what type of butane do you use, how many times has it been refined, and how many ounces?

Is triple refined good enough, or do I need to find a more refined one?

I saw a 12 pack of 3 oz cans of colibri premium butane for $75. Seems pricey to me but I don't know how much it usually should go for. Plus if I need to use 3 or 4 cans I don't think it would really be worth it.

Actually just google searched for it and found a forum with this:




I found a way to test if your butane is pure or not.

Spray a spurt on a mirror and if after it dries there is a "smelly crusty" residue it is not the type of butane you want to be using.

The "type" of butane you want is "N-BUTANE"

the cheap "toxic" type is "ISOBUTANE"

some brands that are good:
COLIBRI, NEWPORT, CORA, CTC, COLTON, DUNHILL, DAVIDOFF, FACKELMAN, WIN, NIBO, SAROME, CALOR GAS MATCH, UNILIGHT, K2, SUPERGAS, VENTTI, VECTOR


Also, here is a guide for how much butane to use with how much skuff ot bud

Plant Material-|-Recommended amount Butane-|-Estimated Yield
1oz High quality bud-|-12oz-|-3-6g
1oz Average bud-|-10oz-|-2-4g
1oz low grade bud-|-9oz-|-2-3g
1oz high quality trim leaves-|-12oz-|-3-5g
1oz trim & leaves-|-10oz-|-2-4g
1oz fan leaves-|-8oz-|-1-2g





So does this sound like it is right? I'm probably going to use some decent bud. Not top shelf but not crap either. And only an eighth or a quarter. So a can of about 3 oz would be good enough for either of those amounts right? I have always seen videos where they use a few cans and it doesn't start running out the pipe until the 2nd can.

If you get caught doing this say goodbye to freedom as this process is treated the same as cooking meth or processing coke/heroin.
There is no medical defense for this process.

Do bubblebags of hash or green dragon if you want to make concentrates.

well auctually making hash or possesing it at all is a felony regardless of the method.its considerd manufactured cannabis.but for the question at hand,using butane really is a waste of time and money,plus the out come is pretty weak.u can buy great bubble hash for less than it would cost u to make it with butane,imo.

In order to not end up smoking residual butane in your concentrate, you need to have a deep understanding of chemistry. I highly recommend you do not proceed without proper knowledge. It can seem to be really good, but the butane will get you high as well. This is very harmful.

There really is no reason for the amatuer to concentrate cannabis using butane. As mentioned above it really is terrible for your health to smoke any butane residue. Why not keep the process natural. Take advatage of the fact that THC isn't water soluable and buy or make some bubble bags. You can always press it up afterwards to change its texture/consistency.
