Hi!! ive been making some extractions (mesc, DMT) and had never failed like this time... I used the exact same method than before (CYB salt max ION tek) the problem is that i let evaporate all 6 pulls till i got half of the liquid then freeze but nothing precipitated out.....

I tried it again this time using a hot water bath on the flask... and yet nothing.... only the naptha is cloudy but no crystals forming.... PH is OK.... should i add more salt??? more NaOH??? I still have the basified slurry....

How long did you leave the pulls in the freezer? and did nothing precipitate at all? not even any oil or anything? Is it possible that you didn't add enough lye for the dmt to freebase? Salt and warm baths do help in pulling the dmt but you should be getting SOMETHING regardless of whether you used salt or baths at all.

Sounds like a bark issue.

Like you have something that's not. ACRB or MHRB?

Volumes and quantities of bark, base, solvent, etc ? At a guess you could still have a high proportion of naptha from 6 pulls (depending on the volume used) preventing it from precipitating. Could be a number of things though, tell us more.

I had this problem wen I started , follow extraction Cybs TEK naps goes cloudy whilst fanning pre freeze precipe and nothing !!
Either very poor quality stem and trunk bark or just bunk all together !! It's obviously not you're technique as you said you've had no trouble before , and you can't go wrong with Cybs TEK , 100% bunk !!

I did evaporate a lot of the naptha... now i only have like 50 ml... it gets cloudy in the freezer but nothing precipitated... its been 3 days in the freezer and nothing...

I also used ph measuring strips to check ph and its seems ok... (PH 12). the guy who sold me the MHRB says it is a very good root.... (it is purple)

im gonna do that and ill be back to you folks

thanks for the quick reply
