Hello everyone I'm having difficulties with my last extraction, I couldn't find any clue on the forum so hope you can help me:

My usual method is based on Cyb's Max Ion tek, and I use Limo to extract the full spectrum. So I salt the Limo pulls with vinegar, let the vinegar dry, then I make a sodium carbonate paste, let it dry and pull with IPA. I always get around a 3% yield of goo.

Here is the problem: my last yield was too heavy (6g when its usually 3g), so I realized a big part was sodium carbonate that was carried away with the IPA pulls. So I decided to dissolve it again in IPA, to decant the sodium carb so I can separate it from the IPA. But when I added the IPA, these crystals are not re-dissolving. As you can see, they're mixed with sodium carb.

Picture 3: separated the IPA from the crystals, and crystals were fully dried apart (they're mixed with the sodium carb) https://imgur.com/wm2gvhO

What are these? I thought they might be DMT crystals, but why they're not re-dissolving in the IPA? What happened here? If these crystals are DMT, how can I separate them from the sodium carb and dissolve them back in the IPA? I've no idea what happened or how to proceed, please help!

Almost certainly sodium carbonate, maybe sodium acetate. Probably there was too much moisture in your IPA (and maybe a bit hidden in your rebasing paste), allowing one or other of these salts to dissolve in it. Try adding a drop of vinegar to see if they fizz. That would show it was carbonate. You could carry out a simple flame test. Intense orange-yellow will indicate the presence of sodium.

I thought the same, the sodium carb paste wasn't fully dryed when added IPA.
So if these crystals are sodium carbonate or sodium acetate, should I discard them? Or is it possible to be DMT in there?

Give them another couple of flushes through with a little DRY IPA. The procedures for drying (i.e. removing water from) solvents are explained multiple times throughout the forum.

And please be patient about receiving an answer - many of us have lives beyond the Nexus!

My apologies! I just didn't know if I was posting in the right topic.
A few more flushes with IPA solved it! The crystals were separated from the goo, and the final spice is powerful as always, so these crystals are not DMT (if they are, it represents a really tiny part).
Thanks!
