Has anyone here tried just decarbing the crude ethanol in a regular oven for 30 mins on both sides, w/the heat set to the boiling point of ethanol. Does this purge out the rest of the ethanol?
I did that and it got it to a point where i think i could low temp purge it in the vac oven.
I seriously wish the place that tests any cannabis products didn’t “require an 8th” for testing.
No, carbon will not remove water. You need molecular sieves for that.
Decarbing?
To remove ethanol?
They can co-occur…to a degree.
They are not the same process.
Generally you’re not going to reach decarb temps until the ethanol is gone. Decarb at 78C happens, but not quickly.
You mention “both sides” as if you’re trying to purge shatter. Most would be explicitly trying to avoid decarb in that situation.
Is “purge” the term you were looking for?
but would it be effective to do that before trying to purge it in the vacuum oven?
Depends what “both sides” was about.
Decarbing shatter reduces the viscosity (makes it runny). Such that decarbing “both sides” is probably not gonna be a joyous adventure.
If the object is solvent free decarbed crude, decarbing under vac will get you there. If the object is a stable shatter that passes residual solvent testing, decarbing in or before the oven is not going to get you where you were aiming.
Or more succinctly: I don’t think I understand the question…
Rotovapped my stuff into an oil. Then I set it to 175°f in my regular oven . for 30 mins on both sides. I did this to claim. I ended up with a semi stable oil that when dabbed doesn’t taste like alcohol or do any funky eye burn shit. Which led me to get believe that one can just bake out the alcohol from an oil and then purge it in the oven @ a low temp to get rid of the rest of any solvent that may be left.
Cause it gets it to a wrap and snap.
Would most definitely be interested in that!
Yep. That will work.
you’re not decarbing. You’re purging.
With reclaim, you were ostensibly decarbed when you started.
If ovens were not a valid choice for this, cascade would not have built one specifically for this industry.
So what temp would I go for decarbing under vacuum to achieve solventless crude?
Can you re run it through a reflux still and achieved desired proof ?
I would usually say yes, because 95% ethanol (“azeotrope”) is the desired proof.
However, if I recall correctly, you’re asking about Isopropanol, and aiming for 99.5% which is higher than you can achieve with distillation (~91%).
Which is why you were pointed at molsieves.
You could also google “salting out”.
why do you find Iso preferable?

Got ya , makes more sense now. So I’m basically achieving 180 (90%). Would 180 severely diminished % of soak yields ? Mainly iso because for the price. Tons of good info from that link forsure. Was focused on getting this rough cut step done and making more appropriate decisions after that.
don’t use a gas oven lol!
Nahhhh its all electric. No flames at all on my oven.
I’d have a hotplate area setup near a window if I had a gas oven.
I’ve recreated this experiment 3 times in the last month using regular material, you’ll lose color but you’ll retain most the terps.
I place it on dry ice for 30 seconds prior to the flip not runny at all. after the second 30 mins on the flipped side i take it out and i dab it. honestly i see no need to purge unless you taste alcohol. but by doing what i do t’s mostly flavor town.
I’d still argue you’re primarily purging not decarbing… although there is probably a line there that you’re dancing pretty close to.
Without analytics I’m just guessing.
I’m not arguing that i’m purging not decarbing i thought baking down an oil in a regular non vacuum oven nmw is pretty much decarbing, i thought purging was specifically left to vacuum chambers/ovens, my bad on that
i should get my next batch tested for terps
Your goal is to get rid of the solvent?
Or to make it orally active?
You don’t need it decarbed, you do want it purged…
I agree you’re going about it non-traditionally, and achieving some of one while aiming at the other.
Given that the purge is deliberate/the desired outcome, and any decarb is a side-effect, I know how I would label the process.
Not really concerned if you want to call it something else.
Crawling back in my hole… 
To get rid of solvent and to keep terps.
