Iso+butane combined extraction?

Hi guys,

I was thinking to try something....I got issues to extract all the goodies from moroccan kief while doing butane extraction, that's why I was thinking to pour some iso in my loaded tube (with a syringe)1 minute before to blast with butane....is it a good idea or am I thinking wrong?

Thanks

Iso is very aggressive. It should only be in contact with plant matter for seconds at a time, otherwise undesirables will be extracted as well as actives. Ethanol would be better as it's less aggressive, but then I don't know if it would serve any purpose alongside the butane.

The ethanol mixed with butane in the evap dish would serve the benefit of helping boil off the butane.

I would say just do straight ethanol washes on the hash. Freeze everything for 24hrs and keep frozen while working. I'd recommend a total of 20 minutes soak time, 1-10 minutes and 2-5's

Ditch the butane bro. Butane has a number of inherent problems; the way it behaves with water (to have butane form an azeotrope with water, which would allow both substances to boil off together would require one of a certain few third chemicals to be added anyway), mercaptans/impurities/mystery oil and explosion risk.

You can make better extracts using ISO alone or ethanol alone. Butane is really stone-aged stuff when it comes to extracts and if you aren't getting properly refined n-butane and controlling for moisture/fire/explosion risk in a proper lab facility/dispensary, you should be using another solvent.

Also if you've got kief already, have you considered doing rosin tek with that? You'll find you get terpier results more easily this way (not to say that this can't be done with solvents - it can - it just is much more of a challenge to get just right!).

I thought the combined action of both solvents could help to extract all the goodies in one blast, plus the "easy to do" bho method...

I know about explosion risk, luckily I live in the wild, no neighbours and a lot of place outside. About impurities in the can I know that...there is different opinions about it, which brand are the better,...I can say I made a test with the tane I use (newport)...I can't see nothing...although I didn't weight the dish before and after to be sure...
About water, moisture, humidity, I learned and choose my days and wait to get very dry buds (but I have a question: what about live resin which fresh frozen blasted buds...isn't it?)

It's easier to get butane than high quality ethanol or iso where I live!

I was considering to try rosin and made a test with moroccan hasch....without sucess, I need to learn a bit more about this tek!
Some questions about rosin:
-how many time to get a full gram of rosin from Hasch? flowers?
- how much will cost the basic equipment (I only own a clothes iron, my wife don't use any hair iron!)?
-The taste is it comparable to bho (I heard the taste was less good...)?

Honnestly I like bho cause it's easy, cheap, yield very well and tasty as hell......honnestly I would prefer to dab full melt bubble hasch or dry sift but it is so long, awkward and yield so low....

Have you ever sprayed some of your tane on a clean Pyrex and see all the shit that doesn't evaporate?

OMG i thought i was the only person that preferred ISO over butane. The internet is full of 'butane is the only way'. IMHO butane is used to be lazy, at least I only extract using butane when I'm pressed for time. (for me it's less prep and set-up).
I've never used ethanol before, not sure how accessible that is for me???

I have to make my own extracts because I don't live in the states with fancy shops
... I always find my finial product is always better using ISO over butane.

I can't speak for rosin yet however I used to use both butane and alcohol in my extractions.

I hate extraction tubes so I preferred the "mason jar" method. Basically you empty a can of butane into a mason jar or better yet a stainless steel thermos and soak the buds in the butane. I would then drain and filter the butane into a dish with a couple ounces of alcohol. Then I would wash of the same material with fresh alcohol and filter it into the same dish. I recommend winterizing your concentrate before consumption when using butane, it never hurts to do the same when using alcohol though.

Running my material a second time was virtually impossible given my living situation at the time and I didn't feel guilty throwing out my bud after running it with two different solvents as opposed to doing a single extraction. If you're going to do an extraction with butane and alcohol you should do the butane run first as you don't want the alcohol sitting in your buds while you prep the butane. The butane also has the benefit of keeping the buds nice and cold for the alcohol extraction that follows. I only did this for convenience but don't see the harm in using this method if you plan on winterizing afterwards.

I rarely dab so I don't mind using butane but it should definitely be avoided if possible. Don't believe in the mirror or glass tests... even if it evaporates without any residue on the glass there's still shit in the butane that you don't want to heat and inhale. Pure n-butane is a different story though...


Regardless of the number or type of solvent I used I never produced anything like @herbivore21 does but I was working with very limited supplies, lower quality buds and an unrefined technique compared to him (and still would be if I was still making concentrates). What @herbivore21 produces from ISO proves that there isn't any advantage to using butane as opposed to alcohol.

190 proof everclear from your local liquor stores. Some states only have 151, which has too much water imo.
There's also organicalcohol.com

Don't use ISO

I've sprayed into a dish with everclear at the bottom to help remove tane. Winterizering is way better but more time consuming.
