Issue with freeze precip for STB tek

I have been doing my first mhrb extraction with natureboy's STB tek and have been following it exactly but my naphtha has been refusing to form crystals since I put it in my freezer last night.
I have no idea what I did wrong. I even left my jars near a space heater for 24 hours when I added the naphtha to the basified mhrb.
 Here are some photos, it seemed like it was going so smoothly before freeze precip the naphtha was hardly yellow and jars that look cloudy are just because of frost on the outside. my freezer isn't terribly cold but it forms ice cubes somewhat quickly and I've heard that if it can make ice it will be okay for a pull.
Can someone please give a brotha some advice

Try to evaporate your naptha solution. If it's not saturated enough with dmt it wont freeze precip. A rule of thumb I use is to make sure the naptha is cloudy when disturbed or blown on then it precipitates no problem

Not the best photo but this is it after I used my coffee grinder. It was in chunks for the most part to start. It created a lot of purplish dust.

How long was the naphtha in with the bark/water and did you stir it around any?

 Here's another photo of the remaining shredded/powdered bark. The bark is used for the extraction was strictly shredded though. I left the powdered bark in a bag.
The napththa was in the bark for about 28 hours. Swirled the jar and turned it end over end probably 8 times during that time. Then went straight to freeze precip
I have a kilo of bark on the way so I really wanna make sure I know what I'm doing rather than waste even more precious bark

What's the MHRB, lye and water ratio that you used? Try combining all your naphtha pulls, evaporate it down to 50% and try precipitating again. Also putting it into a warm water bath while pulling helps. And one can be a bit more vigorous with shaking the jar, if you have no dust and put it into a warm water bath for separation there should be no danger of an emulsion forming. Otherwise your procedure looks fine to me...

Don't know if it's the white-balance of the pics, but my MHRB looks more reddish. Almost purple. Not a classic brown /tan tone at all, especially when shredded.
If there's dmt in your bark, then you should have at least some tiny crystal flakes somewhere on the jar. But I don't see anything. That's strange indeed.

Thank you everyone. I ended up pouring all my naphtha back into my jars and then giving them heat baths. The naphtha is noticeably more yellow now. Jars are in an 82 degree room and will do another pull in 12 hours or so. I am really hoping the issue is that my bark simply needed more time to sit and break down more.
So I think I saw a couple tiny crystals floating and in the bottom of one jar but yeah I dunno how the hell I haven't got anything yet. It's like growing mushrooms is easy for me but this has me so stumped lol..
The kilo of root bark i have on the way is from a different source, thankfully, in case the issue is with this bark for some reason

Why would the DMT Freebase not precip out of the solution, if it is not saturated enough? It seems like it is not soluable in naptha under certain temperatures anyways and the saturation of the solvent should not change that, right?

The solution needs to be super saturated.
It’s the same principle among crystallization techniques of other substances. It is too diluted to form when there is too much solvent.
Your naptha doesn’t look like it contains many alkaloids if any at all. Too clear.
And I would personally freeze precip in a Pyrex instead of mason jars.

Thanks for the tips everyone. Big worm, is it safe to keep my frozen foods in the freezer while the pyrex is in there? I just have nowhere else to put them.
So I made took another pull and put it into 4 jars, probably 40ml in each. The surface seems to look slightly crystally and reflective after 6 hours in the freezer.

You think the pyrex baking dish is still probably the way to go huh? I'm game for trying it, I just want some fuckin spice bad

When I would keep my Pyrex In the freezer with naptha , the ice cubes that were also in the freezer would smell and taste like naptha. But it was also in an open bag.
It’s not ideal. But Ive had many Pyrex’s in freezers with food and it never seemed to be an issue for me personally. But other people may have a different opinion.

Word, well I'm not one to worry too much about that kind of stuff. My biggest loss will be half a pint of ice cream lol, I'll just throw the meats in the fridge.
I'm gonna let it freeze precip in these jars overnight, check in the morning, and if I still have nothing I'll put it in a pyrex and try again
Thanks for the tips

No prob.
How you can tell when the solvent is super saturated. I turn off the fan that I have blowing on the Pyrex to speed up the evaporation. And blow my breath onto the solvent, how you would if you were gonna make a “hot breath “ is the best way to explain it lol. Kinda like how you would if you had hot food in your mouth to cool it down. And you will see that it starts to become cloudy. That is a sign of super saturation.

I advise you to keep the precip dish closed. This is to reduce the risk of water and subsequently contaminants getting in the solution (and as the water freezes) also in the final product after you pour of the naptha.
Also letting it freeze longer (48h and up) might increase the rate.

It’s the same principle among crystallization techniques of other substances. It is too diluted to form when there is too much solvent.
Someone i know that is making DMT usually goes a little over with the np-solvent (10% additional per pull and 4 pulls) and still manages to get good freeze precips.
Now that you say it though, when i went to his place last week and saw the naptha pulls, they did look very clear. Will ask him how it will turn out.
But then again: If you ever put pure white DMT chrystals in a solvent at good saturation, like 30-40ml/g you would see that it doesnt really change its colour. The orange/yellowish tainting of the naptha you describe might be the result of impurities like plant oils and other alkaloids. This could be from using ACRB or very young MHRB or MHB and doing STB instead of A/B.
I do believe the A/B Teks i saw often had quite clear non-polar solvent in the end. This is as A/B gets out the plant oils etc. quite early.
So OP might just be dealing with some very good MHRB.
OP might just be dealing with some bark that is low in fats.
Edit: Gonna double check on the changing colour while resolving part. It is definetely true for polar solvents like iso, but it might be different for the non polar ones.

Ah that makes sense on trying to keep the pyrex covered, thanks for the heads up. I'll give it another day and a half
This is all so new to me.. I do believe my mhrb is indeed legit though. The only thing I didn't measure exactly is the napththa when I put it in but I poured it to the bottom of the wide mouth as suggested by some folks in the thread. When I drew up what appeared to be exactly half with the turkey baster for freeze precip it was indeed 75ml.
Still got 50g bark to use until my order gets here next week so if all else fails I'm gonna give it another go and post it here.

Appreciate it. DMT extraction looks like a fun process which requires a very different procedure from growing mushrooms. Its good to keep track of naptha. The consensus on most STB Teks is to use 1ml naptha per 1g MHRB. Edit to clarify: this is the amount per pull, not the total amount of naptha So going massively overboard (like 2x+) could induce the free precip problem that was mentioned earlier. How much MHRB did you use, when you had about 150ml naptha?

This is a very good amount of starting material to play around with. It's enough to get you some smokeable final product but not so much that it is a big loss if something goes wrong. I heared of someone who lost like 10g DMT in failed salting attempt.
If you are having fun with the extraction and consider, doing it in the future: a friend of mine would advise you to get straight into A/B extractions. They are just marginally more complicated, but make the process quicker, yield a purer product and eliminate the problem of emulsion.
If you want to do STB still, you might want to look into Nomans Tek or its adaptation "The Super Secret Hidden DMT Extraction Guide".
And always make sure to wear safety goggles when dealing with NaOH. Skin burnings are no big deal but you don't want it to get into your eye

I used 100g of shredded bark and 100g of lye in my recipe with 600ml distilled water. Thanks for all that info on the napththa, I will definitely be more exact next time.
I will look into A/B for sure. STB was very appealing because I'm a super noob with this and I live in a really small space with a gas stove.
Giving it 24 more hours to freeze right now. Not even gonna look at them. I have a good feeling about this. I will post pics tomorrow morning
Thanks again everyone, couldn't do it without yall

I had great results with a 1:1:10 ratio, i.e. 50g MHRB, 50g lye, 500ml water. This is nice since it gives a pH in the area of where DMT is just about 99% freebased. Your solution is much more basic, it's quite strange that your Naphtha does not have a yellow color, as I would have expected it to pull even more other stuff. The amount of Naphtha is not really relevant. Just use something between 50-200ml which you can easily siphon off from the mix. If you use more, more DMT will be extracted in one step (but it's less efficient than many pulls with less solvent). But since you can reuse your Naphtha this doesn't matter.
