Hi all, another extraction issue I've just encountered - this time after freeze precipitation.

So I have pulled the naphtha out of the freezer after about 18hrs, when I put it in the tray it was clear, but now there is a slightly yellow/cloudy liquid remaining.....but not crystals. So at this point I'm wondering what one can do at this point and what might be the cause for it? From what I can tell I would assume it's DMT but it's still in a suspension/floaty stage.

Any suggestions on what to do?

I would also assume that cloudiness is suspended DMT.

I'd put it back and let it settle for another 6-8 hours...

Thank you for your advice, I've been posting a fair few questions on the forums, most of it is boiling down to having a hard time explaining what's actually going on, so a big thank you for taking the time to reply to this one.

Another question; in your experience is that a sign of something that could be avoided during the extraction? Or is it one of those unavoidable things?

Make sure the solvent is super concentrated by evaporating until it becomes cloudy before freeze precipitating otherwise the crystals won't crash out.

To answer OPs question, I'm missing too much info I think to make too much more of a suggestion (type of plant, type of solvent... Amount of each, procedure followed ect.)

As for evaporation of the solvent, I've always used clean evaporating naptha.. I get the whole mixture as hot as I can with a boiling bath while mixing, (usually about 50gs of bark used, maybe .3L-.5L of naptha) separate whole still hot, and it has crashed out as the naptha cools to air temp, then into the freezer for at least 12 hour, preferable 24. Subsequent pulls usually yeild very little to nothing.

The only evaporation that takes place is reduction of the bark soup, and any remaining naptha on the settled DMT. (I'll set the dish after draining the freezer naptha in front of a fan at room temp for another 6-12 hours, naptha smell usually disappears after an hour in front of the fan, the rest of the time is just to be certain.

Thanks for the reply; for better clarity:

MHRB (powdered) x 50g
Naphtha (shellite) so 100% hydrocarbons x 50mL per pull
Cybs Salt TEK

Basically I have done it twice and followed it more or less to the letter (I say "more or less" because in the first run I had some confusion with the adding/mixing of solvent stage in particular time and as a result, probably didn't actually do what Cyb had intended).



You use 300mL - 500mL? Does that affect the extraction process?



Based on that, am I correct in thinking that you have your mix sitting in an open container to boil off excess naphtha?

Thank you for that; that actually explains a lot, as I'd pull out the naphtha but it would be clear and yet still had that "new sneaker" smell to it, which according to the TEK was the indicator of DMT, based on my interpretation. And in this particular case, I put it originally in the freezer (clear), then poured what was remaining into a collection jar. At the point of pouring into a jar it was actually cloudy which I believed was because some of the naphtha had been evaporated. What I thought originally was that the DMT would crystallise independently of the naphtha (similar to oil/fat solidifying in water).

IME, it doesnt matter how concentrated the solvent is. The crystals will
crash out no matter what. Even 50mg will crash out of 150mL solvent.

So as a correction I suppose I'm using something like 150ml-400ml.. I have 200ml left and I dumped the whole jar in last time, so it must have been around 200-300ml as I try to loosen as little as I can.

And this is my extraction glass, I never notice too much evaporation during the pulling process.

Based on that, when what do you think is happening with that I'm seeing?
