My workspace isnt exactly humidity free, its a large shed basically. i performed a acid base extraction acetic acid as the acid lye as the base and did my pulls with DCM, i was left after evaporation with a slightly reddish goop it. its dmt after a volcano vape bag i was in dmt land any ideas for my next pulls to make sure it crystallizes i was thinking making a vacuum chamber to suck the moisture out? or washing it something?

Re-x with heptane (or even naphtha). Afaik, DCM pulls more fats/oils than naphtha, like xylene, toluene, limonene, etc.

i love how quickly dcm evaporates and recrystallizing isnt to fun, defatting thoroughly with dcm or chloroform because they are so similar that would stop this issue correct? chloroform preferably bleach is quite cheap
