____If you follow his instructions to a T, the oil is crap and i wouldn't bother...Napthane leaves a serious residual smell and taste and i have tried all kinds of vapping off and whipping processes to fix it and it just doesn't go away..Acetone actually works better and it sucks..
Chloroform, ether, 100% ISO, or a high end food grade Hexane works the best hands down.
If your doin this for the first time, be very very very careful and have someone around in case somethng goes seriously wrong...I have screwed up a few times making stoned ass mistakes and oversites and have almost blown myself up and/or set myself on fire a couple of times and one time I actually did catch myself on fire so be super super carefull this stuff is no joke and the flame is virtually invsible and the oil will make it stick to you as it burns off..fuckin hurts

______________________What temperature are you slow boiling at?
UV light destroys cannabinoids, so I recommend keeping it out of the sun.
If you are going to eat it, I recommend decarboxylating it first, and that will eliminate any questions about residual butane. Stick a container of the oil in a 250F hot oil bath as soon as the butane stops bubbling from the hot water bath. It doesn't look like I have a thread posted on the subject, so I will.
here's a link to 1 gal of 99% ISO w/1% water. Any suggestions on where to start to do the ISO way the best/safest?

Try Safeway and Costco.Thanks... (we should be looking for 99.9% though, right?) - do you know who has that?

Hi Graywolf,
I know we've exchanged posts before...If you stick the oil in a 250F hot oil bath (double-boiler action), I know that will destroy some terpenes, but will that create a stable, good product? And then no need for the vacuum purge? And, of course, then you could dose it for cancer patients? (all theoretical of course...)
ps - W/ ISO, is there an advantage over butane? I started to re-read this whole post, and I'm a little confused on what's best. Butane seems to work great...w/a good, long, heated vacuum purge. Texas (?) w/all those bottles of oil, and it looked like he was doing his purging on an electric stove, looked great, but now I don't know what to think...

___We purged and decarboxylated in a 250F oil pot, long before we started using vaccum purges, and none of the test panels ever detected any residual solvent. We have also supplied a boat load of oil to cancer patients using that method, so its not theoretical anymore.
We like butane over ISO for extraction, because it is non polar and easier to get a pristine extraction with and purge afterwards for most people. ISO can make a pristine extraction, but details and control are far more critical, due to it being a polar solvent.
Our test panels rated QWET and QWISO as more flavorful than butane extraction, because it extracts and retains more floral overtones, while the non polar butane extraction overtones are hashy, with floral undertones.
Both seem to work well.

Impressive knowledge. Thank you for the info. I don't know what QWET or QWISO are....(ethanol and isopropyl alcohol?)
i'm not a scientist but i thought that 1 ml of water = 1 gram, i was also under the impresssion that oil floats on water doesn't it mean it's less dense? i was hooking some ppl up thinking 1 ml was slightly less than a gram, i just he got hooked up.A gram is just slightly less than 1ml.
thanks for the info i made this bases on the youtube vid, it's a great smoke as well, giving it to my friends dad that has cancer in his stomach.

my friend accidentally washed a tin with 2 ml or so oil and some of the oil floated and some sank : P
i didn't google anything that i wrote so it's probably all wrong anyways
Damn straight. Make the world a calmer cleaner healthier PpPgreat post!
damn shame Ricks a fugitive, he is a hero as far as Im concerned!
The first time I made this I used trim. Works great.If you watch the vid it calls for bud. I think you'd have to use a shit load of trim to get anything. He uses a pound of bud to get a small amount of oil
