first I'll say that there's no such thing as a selective single solvent system. chloroform, dcm, and tce will pull other components. the advantage of using them is less is needed, and multiple pulls are likely unnecessary (I typically use methylene chloride as 1/10th the volume of the aqueous phase, single pull) and you don't need to heat them.
that being said, you'd probably need to order them, or seek them from a local small chem supply store. Methylene chloride is used for welding PVC and acrylic.

you may still want to re-x your product, which may be light yellow or pink, and resinous.
you could use either naptha or heptane for this.

Thanks for the help. Still have a large supply left from my last extraction.

But I'm starting my summer job soon and will have some more money, and what better way to spend it than being chemically efficient on my extraction. Might as well just make this my full time hobby....never liked model airplanes anyways.

Also, know several welders back in my home town, maybe could get one to order/get me some without raising any eyebrows.

these chlorinated hydrocarbons are common in industry, not really used as precursors. You can obtain them legitimately. however, they wreak havoc on water systems, so don't EVER pour them down the drain.
if you're really considering this as a hobby, consider getting some glass (distillation apparatus) to redistill your solvents. it's one of the most ecofriendly things you can do.

Actually have been working on acquiring a distillation apparatus various pieces of glass at a time. For a different project. Good to know about the solvents. Going more green would also probably be a good goal to have for all of this for me. Thanks for taking the time to reply benzyme!

Just took the first batch from yesterday's extraction out of the freezer. Poured the naptha out, and am letting it hang dry to get the excess naptha out. Is this looking okay? I have just enough solvent to do a re-x, because these are looking pretty gnarly, but it's the best results I've gotten so far.

in a watch glass no less. impressive.

Thanks? Haha. Its the only thing I had left. What would you recommend? And after all of the naptha has run out/evapped, I should just leave it alone for a while, correct?

honestly, that product looks good to go. vape-worthy indeed.

Just make sure it's one hundred percent dry and you can smell no traces of solvent. I give it a couple hours in front of the fan. If you think maybe its a little moist yet, keep drying it. Better safe than sorry when smoking solvents.

Are those crystals staying solid at room temp? Starting from mimosa it looks like *maybe* you have some plant fats in there. It's impossible for me to know for sure of course, but that's just what my best estimated guess would be. If they get mushy at room temp this is good evidence towards that case anyhow. Re-x would solve that.

If they stay solid at room temp, I'd say that those look good/great to smoke, I'd vape em with ya anyhow.

Congrats on getting some crystals!! You're almost there!

So while I left that upside down, I left the house for a bit and most of it melted off I grabbed all of it, dissolved it in a little more naptha, and then put it in the freezer again.

Now the batch that I had made last night is full of crystals...and I don't want to make the same mistake of leaving it out and having it melt. It's been in the freezer for over a day, is a light-yellow color, but still kind of slushy...holding it at room temperature upside down even for 5 minutes allowed some more naptha to roll off.

Any suggestions?

Here's a picture of said collection jar.

Just to clarify, this is batch two? Batch one being in the freezer again right now? That's what I think you were saying, so I'm assuming this is the case.

If the DMT is "melting" at room temp, its probably leftover plant fats, and re-x would do wonders, small jar, lil bit of solvent from a hot water bath, then swirl gently till dmt dissolved, tilt to one side until yellow gunk forms, then pull solvent without getting that yellow gunk. Then re freeze precip.

If it was upside down however (I don't know what a watch glass or whatever that was is) and naptha was drippin off, do you think the naptha could have been carrying the dmt down with it?

I usually leave my collection jars, or pyrex, or whatever right side up, in front of a fan, until they're bone dry. If you can scrape those crystals onto something flat without having a fan blow them all away, that'd work good too, I used to scrape crystals immediately after decanting and put onto coffee filters(not a good process), would put that a foot or two behind a fan, allowing good circulation for drying.

Once dry, if still like gunky and mushy at room temp, then fats, but if dry and powdery or like soft, then good to vape.

EDIT: Even if the dmt appeared to be melting, if you scraped up all the gunkiness that was left, you have all the spice that was there. It can't just evaporate, that'd be beyond the laws of physics. Unless it was dripping off in the naptha as it was upside down, in which case, some may be gone or whatever.

So I took it out of the freezer again and left it out with a blow dryer on cold running over it, and within 10 minutes, this is what it started doing... are you saying this is okay to smoke? Or what should I do to it.

FATS! This is my opinion anyway, someone else may have a more educated guess than I no doubt.

Re-x. Take a small amount of naptha ( I believe this is the solvent you were using), prepare a hot water bath, get it just a little bit warm, add it to that, or add that to a clean jar than add the warm solvent, shake gently, tilt to the side until yellow gunk stuff forms in one corner, re pull the naptha(I tilt or pour out as much as possible without disturbing yellow gunk then used turkey baster or syringe to get the remaning solvent out) IMO I'd rather leave a little solvent at this stage and sacrifice tiny amount of spice, rather than get any yellow gunk in my final product.

EDIT: Add solvent in small amounts to use as minimal as possible to dissolve all spice, then after pull, immediately go onto freeze precipitation of PURE spice crystals.

Also, some of my more "adventurous" friends have smoked gunky spice like this(just stored in freezer to keep in crystals right until vaping) they say it works well with little ill effect, but I personally have never used the fatty spice and wouldn't either.

I'm going with compound on this one...

My 3rd pull looked a little like this and I ended up just tossing it....it was a little too gunky and would not evap into solid like my first 2 pulls and my 4th pull. I wasn't going to chance it as it still smelled like solvent and I wasn't going to go through a whole bunch of hoops when I had 3 out of 4 pulls turn out okay.

Results from my first extraction? 1.1g of beautiful spice from 100g of Mexican pre-powdered bark.

TOTALLY happy with it. Going for the gusto on my next extraction!

Best of luck to you in yours!!

Just did a re-x. Here's what it looks like before going into the freezer! Fingers are crossed. Thank you to everyone for your help so far!

Sounds nice Cain, have you considered using shredded bark instead?

Looking GOOD data, real milky.

Post a pic when they're all grown up. *tear* happens so fast, known em since they were . that big.

Haha I think with the other batch (that's still freezing from earlier) I'll just go straight to re-x and not take any chances with it melting.

^sounds smart. Or else idk your process, but sometimes getting the naptha off REAL QUICKLY when getting out of the freezer can help a little bit with keeping the fats out of the spice. like REAL QUICK!

I will probably go that route with my next shipment. I'll also go with Brazilian so I've got both kinds for comparison.

The pre-powdered I've got is fairly chunky and fiberous but I like the idea of using more shredded and being more hands on with the process. I enjoy the extraction process almost as much as the smoking process and I take great care and time in doing it.

I'd mentioned before somewhere on here that I wasn't following a tek anymore. I got basic measurements on what volume I should be using but found that it'll pretty much let me know on it's own when it's ready, so I go with it. After I stopped measuring things it got so much easier...no spice melting before my eyes!

Plus, when I do my freeze precip I use a walk-in freezer that's almost continually at -10 degrees and it never leaves the freezer when I dump the solvent to continue the process.

I'm really happy I got 1.1 off my very first extraction only using 100g. I'm excited to see what I end up with on the other 370g!
