A UK ebay supplier.
It was much cheaper than anywhere else.

Don't worry about the bark quality, it's the technique of extracion that's not giving off good results. If you're a beginner I can strongly recommend q21q21's tek for some nice white crystals, and it's way easy to do.

If this was from powdered bark STB, it's similar to an extraction problem I've experienced. I'll get nice white crystals on top of a layer of goopy stuff that precipitates before the crystals.

My best method of cleaning the precipitate is hot naphtha. Collect the goop and crystals, put in small glass like a typical re-x with bestine. Use a hot water bath to heat the naphtha (I melt the dmt along side). Add "several squirts" of hot naphtha, letting everything get stirred up. Cover the glass with dissolved dmt/impurities with a card for ~5 minutes while still in the hot water bath. Impurities will settle out, but be advised that this settling seems to take much longer than typical orange plant oils separating in a re-x operation.

Hope this helps a bit. It's fun to play with brain food.

swim also have used the UK based seller on ebay, not sure if I am allowed to say who by the forum but it was the one based in bristol. swim had the same issue for the first couple of pulls, exactly the same. swim got tan coloured goo and no xtals for the first two pulls. i was using too much naptha same as you too. Got great yield by following this tek, ended up with about 8g of off white xtals.

good luck!

I think it depends alot on where he got his bark, it could have been old or just not a bad batch. Ive never seen thst coler before thsts why I ask. stay away from tht bark

OK, I've carried out another naptha pull using the same bark/ lye solution and just put it straight in the freezer and there are crystals precipitation after 10hours. I'm so pleased that I did not throw the solution out yet. I think I might even do another pull after this one!
They look like nice white crystals.
Many thanks.

STB is so simple in that case. Basify the bark in solution, add naptha, remove naptha, freeze naptha. Can this be so? Why do any other tek?

make sure to keep it over 24 hours in the freeza

Will do Tele. Thanks.

If this continues to be a problem one could wash their naptha before free precipitating. There is definitely DMT in there, but likely a lot of plant fat and other stuff.

When SWIM has overheated his reaction vessel during extractions using STB SWIM often gets extremely yellow or darker colored naptha. SWIM has found saturating water with sodium carbonate then mixing a bit of the solution (maybe 1/2 to 3/4 of an inch) with the naptha, shaking vigorously, and then separating helps clean up the Naptha before your freeze precip. Feasibly you could just use water, SWIM prefers adding the base to prevent losing any freebase DMT to the water.

This is what I was talking about in the tek I followed. Cleaning the Naptha using a "wash."
I have just experimented with a pull and no cleaning. So far so good.
Many thanks.

There really isnt anything wrong with that goo... its just really hard to work with, and really messy and makes your hands all sticky. all you need to do is run a re-crystallization on that and it should be pretty close to totally pure... any more than 1 re-crystallization could just rid of any other dmt, and you're not really gonna make it much more pure... at this point after re-crystallization what you have is about 99% pure dmt. now, im not an expert really, ive only done 2 extractions myself, but im still quite knowledgeable on this subject... first of all, what that goo is, is perfectly fine dmt... its not the purest, but what happened here is that it got ionized. this is a chemical process (i think its chemical) reaction to the PH being too low. you want your PH to be above 8 if possible. if its lower it gets ionized, which is the dark gross goo stuff. i hope that helps.
