If I Decarb under Vacuum, would I avoid Oxidation?

Put 10-1 ethanol mix in freezer for a couple days then filter fats waxed off with a simple coffee filter. Put that on a magnet stirrer until alcohol is gone add terps and stir more. Use syringe to inject in to a cart that’s the basic home tek.

Oh lol. Ok so that’s what I’m doing. I do a Blast then Ethanol in freezer. Filter through 0.22u syringe filter because only working with around 100ml of Ethanol. I purge the bulk of that and the rest. Long and short, I end up with a nice Shatter.

I heat that up, 4% Botanical Terpenes (Not for long, proper ones on the way), heat and mix then load. I let it wick. First and second hit is okay. Too thick to move, won’t bubble. Bad experience.

Take that shatter then put it in ethanol and witerize then filter. And use a good cart.i can make a good shatter cart with no terps added that burns great to the end with ascent ceramic carts

You forgot the decarb step.

I keep losing color and taste as well as a change to effect when I’m decarbing. I was hoping that decarb under vac pressure might limit those adverse effects I was experiencing.

Another option is to change the weaponry you’re using to huff that shit…

@qma; what you got for insight here?

I don’t decarb. Just time in roto to recover alcohol. I would think it gets decarb when the cart is fired. All I know is they are full spectrum and get me stoned!

Have you tested it? Either it’s decarbed or there’s something that shouldn’t be in there keeping it liquid. THCA is just going to crystallize.

It’s not a matter of decarbing when you hit the cart… it’s so it doesn’t turn to concrete

You lose taste during decarb because at the temps it takes to decarb, terpenes will break down or evaporate out of the mixture. Therefore, decarbing under vacuum will only serve to further reduce the terpene content in your final oil because vacuums lower the boiling points of items inside, which means your terpenes will start evaporating out at a lower temp (ie sooner in the decarb process) and faster than they would at atmospheric pressures.

Best way to decarb theoretically would be inside a container that has been pressurized with an inert gas such as nitrogen. Sealed container, so no terpenes will evaporate and be lost to the atmosphere and no oxygen present to oxidize the terpenes that will be swirling around in a vapor form. Once decarb is complete, let it cool down to recondense the terpenes then you are good to go. Although there will still be some thermal degradation of the terpenes I think this would keep the oil as close to the pre-decarb profile as possible. Just spitballing though.

u can definitely make it bubble under vac at lower temps…I can take jar off the hot plate of sugar or shatter I’m I’m decarbing and stick it in the vac chamber and it makes it bubble like crazy. I’m assuming that’s the decarb step

Maybe one hour in roto at 180f is doing it but started with a mag stirrer long time ago and still never had a problem. Not tested just for personal use. !

Ahh! I can achieve THAT color, if not a touch lighter, in a ceramic cart. But, viscosity. I love what you’ve made!

are you using cards with four 2mm intakes?

certainly decarbing some of it at that temp.

I would check that out for residual solvent… only time I’ve seen a slab stay liquid like that without a real decarb it was just runny from ethanol. What’s the consistency of the slab? Pull and snap?

Bho extract
60 hours or so in vacuum oven
Witerized in 99.9 ipa

Shatter has no solvent in it

I have left in oven at 150 for a week before and same consistency

I have consumed up to 1000 within the family and no complaints

winterized then vac oven?

iso doesn’t drop fats as well as ethanol or methanol Iso vs ethonal

No slab goes into 10:1 alcohol then witerized two days minimum then filtered heated in roto to recover alcohol then to mixer for terps if added but generally just heated then in to the cart farmer. No cuts or terps.

that’s is a waste of 60 hrs imo…

No need to purge crude that’s going to be winterized?

I would posit that you’ve also been huffing quite a bit of iso… if you’re recovering your solvent, why not use food grade ethanol?
