Hey guys. My friend and I are in serious need of assistance.

About a year ago, we did our first DMT extraction and we ended up with very pure white and yellow crystals. We were extremely satisfied with our extraction. We followed the DMT For The Masses tutorial. We did not use a freezer whatsoever. We did the heated naptha pull, then we just let the naptha sit out on trays with a fan on it overnight.

So eventually we try another extraction, same exact method, and it failed. We ordered more bark, and again, failed. We have failed on probably 3 or 4 extractions after having done one perfect first extraction. We are following the same steps. Anybody have a clue what could be going on?

Please, do not tell us we need a freezer. We did this without freeze precip the first time, and it worked amazingly. The only thing we think we could be doing is maybe not heating the naptha enough?

Science is science, right? It should work consistently everytime.. or so I thought.

Please, any help is so appreciated. And if anymore info is needed, please feel free to ask.

Thanks Nexus.

So the naphtha just evaporates clean leaving nothing at all? check your PM by the way

On the failed attempts, we ended up with a weird looking brown layer over the trays. But no clean crystals at all. Wish I had a saved photo of a failed attempt.

EDIT: I tried responding to your PM man, but it says new members can only send PM's to Moderators. So I can't.

right on...well if you were using MHRB i have no idea where you went wrong. Maybe provide a more detailed report of your procedure.

I read your question wrong, edited my last post again.

And yes, we always use MHRB.

if that were the case, so many things would be "proven", and no one would need to do further research. that's not how science works. there is plausible evidence, not proof or conclusiveness. results vary.

brown layer sounds like you may have sucked up some of the bottom mix along with the naphtha. srape up the brown layer and re-x with heptane. maybe that'll help. other than that, i have no clue

You still have the layers? Do they smell like spice? Are you using the same vendor each time? How are you doing your pulls? Are you heating the base soup or are you just heating the naptha? How hot are making it (warm/hot/boiling?) Is the layer oily?

If you are doing everything 'exactly' the same...then the only variable is the bark.
Either it is duff...or it is some other type of bark.
Possibly mail the vendor...

Probably the bark since that's the only variable.
Science is science but plants are plants and can have varying amounts of unwanted substances that are soluble in naptha.
You can clean your brown gunk with a more selective solvent like heptane as suggested, and in the future, do the freeze precip - it's a much cleaner way to work.
Also, don't use heat until the last pull. Heated pulls are for the end when you want to extract the last little bit along with whatever other exotic goodies might be hiding in there. They just make your first pulls unnecessarially dirty. More is not better with heat - the solution, not the naptha is what you want to heat and it should be like hot tap water, not near boiling.
