SWIM has been attempting an A/B extraction with Acacia confusa root bark and has great success until it comes to retrieving the crystals after freeze precipitation. After suctioning the naphtha from the basified solution SWIM puts it in a glass jar, and lets the naphtha evaporate to about 70% of the original amount to super saturate it. From there, it is placed in a pyrex dish and plastic wrapped a couple times to minimize evaporation. After a day or two, SWIM filters the excess naphtha through a funnel with a coffee filter. Most of SWIM's crystals remain on the pyrex plate, so from there he turns the dish upside down and places paper towels to catch all the remaining naphtha that drips down. From there, SWIM turns the dish right side up, and allows it to sit for hours for further evaporation. (SWIM uses a separate freezer for this and is well aware of what evaporating naphtha like that can do to food).

SWIM doesn't understand what to do after that point. He has tried to scrape the dish, which resulted in the crystals and a goo coming together, which when left at room temperature evaporated about 80% of the mixture. What was left was a nasty brownish goo.

Should SWIM take the dish out of the freezer and let the crystals come up to room temperature? Should SWIM first put them in the refrigerator so the temperature change is not so great?

Any and all feedback is appreciated.

Swim should do a search, theres countless threads about this type of thing

The search is your friend

Yes, you are right. I posted this because I felt I have spent enough time on the forums, and SWIM has done enough experimenting (losing product) to ask for some help. I even saw your method for doing such activities. SWIMs problem with your idea of taking is out and fanning it until completely dry is that even when all the naphtha is gone, and it has been left to evap, when left at room temp, the crystals melt and turn into goo. Or at least that is SWIMs experience with attempting that.

Well its time to Embrace the goo

If not there is also plenty of info about dealing with goo from acacia.

Most of which include putting it into a small amount of warm naphtha, and putting it back into the freezer. Which would put one back in the same place they started. This is not so much goo, but more small wet blotches. If left out they evaporate completely.

Well if what you have is evaporating then its not DMT. Sometimes crystals will melt into goo at room temp, but that goo won't evaporate.

Which tek are you using?

https://www.dmt-nexus.me...aspx?g=posts&t=51199

It is a slight variation of thick-lights tek.

DMT won't evaporate at all? Even if it was melted into a gooey/wet substance?

It won't evap at room temp.

What is the variation and why are you changing the tek?

Have you extracted before?

You misunderstand me, I think. The linked post IS the variation to thick-lights tek. That is the tek that SWIM is using.

I have never extracted before, and SWIM has done it before using evaporation, although told me that his yields were never good with it.

Sorry I thought you had changed the tek.

Did you extract from the same bark last time as this time?

Seems like that tek should have worked, I would try using a different tek and see if that works, if not then it may be bunk bark.

Also on an unrelated note, Using swim is pointless and provides you with no safety, it just makes post annoying to read.

No worries, "it" wasn't very descriptive of me!

Yes, the bark has been the same as always.

It resulted in white crystals that stuck to the pyrex. There are simply problems with what to do after all the naphtha has been removed. Possibly there is still some solvent left under the xtals? That would explain why they are melting when SWIM takes them out to dry at room temp. The xtals would melt into the naphtha, which would then evaporated.

Of course there is a reason to use that acronym, or nobody would use it. The reason just varies a bit from person to person. Regardless, I'm sorry you're annoyed by it.

DMT won't evap with the solvent, that's why evaporation is an alternative to freeze precip.

Then why not after it has been in the freezer for a day or two, do people not simply pour off excess solvent and let it evap from there?

They do, that's pretty much what I do.

If DMT evaped with the solvent then you couldn't grow crystals using slow evaps, you couldn't use solvent to infuse herbs and you wouldn't be able to reduce mimosa/chacruna brews

Anyway, I would try another tek to see if that works.

This might help, but I'm not certain from your description:
..Enough GOO questions! read this..



Evaporation and freeze precipitation will not effect the yield. The steps leading up to evaporation or freeze precipitation will effect the yield, but the difference between evaporation and freeze precipitation is simply personal preference.



I think you might describing recrystallization? If you are, there is more to it than just dissolving in warm NPS and putting it back in the freezer. You have to lower the temperature of the solution slowly, over the course of several hours, so the impurities crash out of the NPS before the DMT does. DMT will not evaporate at room temperature, no matter what. If there were still solvent in the pan when you set it out to dry, the crystals might dissolve into the solvent, but when it evaporated it would leave the DMT crystals behind. If you are getting crystals but they are melting and then evaporating, you might have just gotten some water in your solvent that is freezing (forming ice crystals), and then melting and evaporating.
