i know this is commonly done with mescaline extractions but i have never heard of anyone doing this with dmt. would it work? and if so it seems like it would be a great way to separate as much solvent as possible?

Allow some of the solvent to evaporate under your kitchen stove fan, making the solution more concentrated, stick it in the freezer for 24 hours with an airtight lid...after which you should have some nice crystals....poor remaining solvent through a coffee filter back into your extraction container...its best to let the container containing the crytals drip dry at some type of angle, simply allowing it to evaporate dry sitting flat in the thawing frozen conainer you used is bad news...condensation will form and mix with your prize....if a mason jar is used simply tilt the used jar upside down into another jar as it drips dry...hope this answers the question.

thanks very muchly for the advice vanilla spice, although that didn't quite answer my question, it did however answer another one that i'd been meaning to ask because i have had this condensation problem in the past.. cheers
i was actually referring to the separation phase of the naptha from the base though, you know how in mesc extracts the base with the xylene on top is added to the freezer, and the base freezes, leaving the xylene to simply be poured off? i was wondering if i could apply this technique to spice extraction. or will it start precipitating prematurely

bit of background. i am doing an A/B extraction on 150g dried acacia phlebophylla phyllodes. (don't worry, i didn't touch the tree, i just picked the dead leaves up around the base). the reason i am asking about this method is because i want to get every last bit of naptha out of there so that i get the maximum yield possible. i feel very special to have in my posession the leaves of a phleb plant and want to get as much out of them as possible

hmm. if spice doesn't precip from cold xylene normally, I don't see why it wouldn't work. That being said, I would test it on some MHRB first (with established potency) to make sure you don't lose any yield.

I'll be honest, this is the first I have heard of freezing the entire container, so I couldn't say if it would work, but it sounds like it would.....if it does I have to say that it is a pretty efficient way to get every last drop. ALthough some goodies could remain frozen in your material/base layer. I am not too familiar with a/b extractions, only stb...in stb lye is used, and I have heard it acts as an antifreeze and is not as easy to freeze, so I don't believe it would work for an stb tek. But for an a/b extraction I could not say?...no matter what you should gather as much out of your jar before attempting the freeze...no sense in wasting. Recycle your naptha (warmed if possible) back into the container until your pulls produce nothing, generally you can feel comfortable the material is spent at that point.

thanks for the feedback friends i'll keep yas posted on how it goes. if it doesnt work.. its not like it'll ruin the extraction will it? will i be able to just thaw it and do pulls with the baster as normal do you think?

also i have used this method with separating the base from the solvent with mesc.. and it froze the base nicely, so hopeuflly it'll work for this. its easy that way cos you can just pour the solvent off rather than messing around with a turkey baster due to not having a sep funnel. looks like i need some new gear

xylene is different than naphtha from what i understand..

you cant freeze precipitate spice out of xylene but you can with naphtha..

so i may be wrong here, and please someone, correct me if im wrong but i believe that freezing the whole thing would cause the spice to fall out of the naphtha before the base freezes solid..

thus leaving you with no spice in your naphtha...

again, not 100% sure, though someone should be along to confirm/deny

yeah i was thinking that might be an issue. so for this method a differen't solvent other than naptha would prolly need to be used hey?

i bought naptha for this extract so looks like i'll have to try it next time. thanks guys
