Are you using an electric vacuum pump in a chamber with a heat gun or what's your setup?

my first try with vac purge
- Thread starter ojd
- Start date
Knotty on The tube, has the best bho "scrape" porn..... Really just amazingly beautiful pre vac *purged massive thick Ooooey gooey goodness. Dudes scraping like 80 g from around 500 g runs.*
You can find a 2 stage 3 cfm pump on eBay pretty easily for around a hundo, a good dessicater (ie container that can hold ) I'm not sure, but small cheap can go mason jar style, and a electric pancake griddle (target, walmart, etc)

Oh and infrared thermometer, found at petsmart for 30, that way you can check griddle temp and also open and check patty/ oil temp
Oh yeah .... Nice OJD

what do you put it in while in vac chamber?
Tuesday in class, we produced a light yellow clear amber using year old mixed trim from a trim pro.
We packed it as was, without futher sizing, and ran three flood cycles, with the recovery pot on the Mk III at 85F.
We washed it out of the recovery pot with a minimal amount of 190 proof ethanol, before filtering and evaporating away the alcohol in a thin film using 115F and -29.9F.
Not much smell or floral flavor, but the extract smelled exactly like the starting material and produced a light yellow shatter.

I am having trouble with oils 'sparking' when held to the flame. This is even after 5+ hours of vac purging thinly (a few mm thick max). temps are between 115-125.
Using a metal poker and a lighter, taking a small dab on the end of the poker and holding a flame next to it. Small sparks pop off the oil.
Plant material is very dry. Butane is a Euro brand. Butane is run through a filter drier.
I am thinking that possible moisture from the tube freezing over is remaining in the oil. Really struggling on preventing this as some strains spark less or not at all after following the same Vac procedure.

keep purging ... IMO 125 is too high, I stay between 95-110. Slow and low. How are you purging ... straight hard vac, or are you vacing and than letting sit while under vac? Spark are due to gas ... perhaps brother gray wolf will tell us different, but this is my thoughts. there's a lot of info on purging over at tokecity.com ... ck it out. What type of pump are you using?
I am doing hard vac with Robinair 8cfm two stage pump (stupid 10gal. chamber). I do not notice bubbles popping below 100.
With some batches I end up warming up the oil to spread it thin which seems to provide rapid bubbling when put back under vac. But as it pools up in the chamber it either turns to wax if kept warm enough to bubble, or stays as shatter and is not warm enough to off gas.
Shooting for a nice shatter.

Ya I need to find some good research about that crackle snapp and pop which worries me.
I was wondering if properly purged oils will still make that sound... maybe just because of being heated on the skillet.
No, I run the power cord through the top stopper.
If you haven't winterized to dewax the oil, it will shoot off occasional burning wax fragments.
Water is usually the culprit when the oil dances and sputters wildly.

Hi GW, I just PM'd you at another forum but thought I'd do so here as well.
I just made Absolute a couple of days ago using this exact method you posted and what I got back is somewhat of a taffy consistency instead of a hard shatter and also notice some of it is starting to turn opaque. Should I continue to vac-purge a little longer? How long do you usually vac-purge your Absolute or QWET?
Thanks in Advance!

It sounds like it is waxing up on you, though I've never had an Absolute do that.
Is it an Absolute or oleoresin and how thick is your puddle?
I cold boil off an Absolute or QWET in thin films under vacuum at 115F. Once the visable alcohol is gone and random sized alcohol bubbles stop being produced, so only the fizzy equally sized CO2 bubbles remain, I remove the oil from the chamber and allow it to harden.
I start with about 1/4" to 3/16" liquid in a 6" Petri dish, and it takes me about one or two hours to cold boil and fully purge a sample, which ends up 1/6"to 1/8" thick and of shatter consistency.
I saved two of them for over a year before scraping, as I used them as show and tell for students to drag their fingers across. They still looked like stained glass at that point, and tasted hashy, with most of the floral flavor was gone.

me neither.....

It is an Absolute... I poured 190 proof Everclear in a small jar and then added my BHO, then placed into the freezer for over 24 hours before filtering it onto a warm pyrex dish. I had a single puddle that weighted about 7 grams or so. I use a 9" bel-art desi as my chamber. Should I have made smaller 'puddles'? If so how small are we talking?

This is what I did as well although mine never hardened...just taffy consistency. how long does it take to harden usually? And does it harden by just leaving it out in room temps without it being covered by anything?

..............I placed mine into a tuperware container before allowing it to dry completely. could this be the reason it is waxing?

so then, should I try and warm it back up to 115* F to get it in a viscious state and place it back under vac until it solidifies?

Sounds like you hit the key points, except for 24 hrs, vis a vis 48 hours for winterization. You may still have some retained plant waxes, providing nucleation points for waxing.
More heat won't harden it if the alcohol is gone. I would put a small sample in a thin film and bring it up to 115F under vacuum and look at the bubbles.
If it still has random sized solvent bubbles, I would cook it until it doesn't and if it doesn't, I would set the sample out in a thin film for a day or two, with something to keep the dust out, and let it set up. Fizzy equally sized CO2 bubbles are OK.
If it is partially decarboxylated for any reason, it may never set up, but should still be good oil.
