So I just took my 5th pull of naptha out of the freezer and filtered it through a coffee filter as usual. The first 3 pulls yielded a couple hundred mg each of clean crystal. The first pull was the whitest, and each subsequent one became a little more yellow. On the 4th pull, I did everything as normal. Put about 4 oz. of yellow DMT infused naphtha in the freezer again in an air tight jar. Retrieved it 24 hours later. Crystals seemed to appear in the now freezing cold naphtha, but they were definitely different than the first 3 pulls. Filtered with a coffee filter. No yield. I was perplexed. What could have gone wrong?

So, I let the naphtha pull more alkaloid from my base solution for the next day. Sucked about 4 oz. of it up and put it in a jar, but this time let it out to evaporate some. About a little less than half of the naphtha evaporated, and the rest was yellow and murky. Placed jar in freezer with lid. Retrieved jar 24 hours later (about an hour ago). Either that jar had DMT crystals forming, or I hallucinated that. But there was significantly more crystal than the first 3 yields. Gee golly me! So, I let it sit in the freezer for about 30 more minutes for good measure. Took the jar out and the solution looked murky again. Thinking this was probably normal, I went ahead with filtering through a coffee filter. The solution took extra long to filter as it seemed like it was clogged or something. Once again perplexed. After I managed to get most of the naphtha filtered out, I noticed the remaining final product was not anything like the crystals I got before. It was more orange, and of different consistency. It was an insignificant amount so I threw it out. So I'm pretty disappointed. I can't tell if the bark has run out of alkaloid or what. I don't get why the frozen cold naphtha with crystals magically ended up leaving nasty orange residue. The filtered naphtha is currently back in the mimosa jar. It's very yellow and murky. I'm going to attempt one more extraction before I scrap the solvent and try fresh solvent. Then if that doesn't work, I'm going to assume that the root bark powder is spent and I'm going to toss that as well(don't care about jungle spice). Also, for the record, I have not added any extra water or lye since the beginning of the whole process.

Does anyone have any input on this? What should I do? What went wrong?

Honestly, after a lot of pulls, I'd guess the ratio of DMT to unwanted materials pulled (plant oils, whatever) is a lot worse. I'm not sure how much MHRB you're using, but it sounds like you have pulled a lot of DMT out already, and that might just be the biggest problem.

Even if there's dmt left to pull, perhaps you're pulling too much non-dmt to get decent freeze-precipitation.

If you're curious, you could really easily evaporate your pulls and see what crystlization shows up. You could re-crystalize with naptha or heptane to try and get a more concentrated product to freeze-precipiate. It's just getting whatever DMT product you have into a really small amount of solvent.

But other than that, there may be more DMT locked away in your bark that simply needs more processing to release. I don't know how basic your solution is, what tek you're using, or anything really, but you can always try more.

You're using STB, so if you want to get EVERYTHING, try adding a LOT of base (slowly , don't shatter your containers) waiting a week or so while mixing occasionally, then adding a moderate or small amount of solvent and vigorously shaking, letting solvent separate, and then maybe repeat the shaking and separating 100 times over the course of a few days before pulling. That's some SERIOUS overkill. But if you don't get anything after doing that, you're bark is near dead, and you should appreciate what you got already! Oh, and if you're doing that much overkill, you'll likely pull a lot of other material... But if you evaporate instead of immediately freeze, you'll have a general idea of how much you have. That might give you more oxidized dmt, but you can convert it back with a little work (just search), but regardless, I'm just trying to help you see if there's DMT left.

I'm just curious, do you have a total amount of DMT you've pulled so far? How much bark was this? Can you give a little more information? 4 oz. of naptha might be too much, but I have no idea how much bark you were using... but with significant partial evaping that's less important. In summary, lots more details!

I'm extremely new to all this, but I wanted to help since you didn't get any responses! : D
