i recently let a naptha/dmt solution set in a 50-60 F temp room for 3 days. crystals started appearing on the bottom, the most clean clear crystals i have ever made. i put it into the freezer and 10 hours later i got the usual white fluffy stuff, nothing spectacular.

so i decided to precip an entire batch this way, by letting it sit. mind you i have a lid on my jar, there is no evap going on.
i tried it and came out with some of the clearest chunks of crystal i have ever made. clear shards about eighth inch long, in chunks. \|/ <<< like so
i have never read about this method before!?
why have none of you done this?

How long did it take? Seems like a week or more, no? Similar can be done with n-heptane in a day.

dmt will crystalize when: a- temperature lowers and in turn lowers the solubility of dmt in such substance

or

b- there is gradually less solvent (because it is evapping) so at some point the solution saturates and then dmt starts crystalizing

Whether its A or B, the slowest any of them is done, the bigger crystals will form

what happened with you people do a lot, yeah.. look into 'growing crystals'. Probably the lid of your container was not so well closed so it was evapping real slowly, and/or the solvent was very saturated and once it cooled down, even at room temperature, it already started crystalizing

sweet! and anybody know the temp at which dmt separates from naptha?

i know mine doesn't evaporate.

it takes 2-4 days, at temp 55 to 70 F.

It depends on how much DMT / how much naptha (or whatever solvent). As either solvent evaps or the mixture cools, there is less naptha available to hold onto the DMT, which causes it to be squeezed out into solid form.

The solvent must be evaporating out for this to happen. Check the lid.

This is called room temperature crystalization. This is a wonderful way to create large crystals during a recrystalization. Instead of sticking it in the freezer, use a small amount of naphtha and leave the lid partially off of it. As the solvent evaporates the solution becomes supersaturated and spice is forced to crash out. If done slowly, and using a seed crystal one can grow large xtals up to and possibly exceeding an inch in legnth.

This also produces more pure spice than freeze precipitation. Something to do with impurities not being able to fit in the crystal latice. Again, this is a great way to recrystalize. I always freeze precipitate first, then recrystalize at room temperature.

sounds like a good crystal growing method if any evaporation is going on, it is very little. the level of naptha does not noticeably change. i think the solution is saturated to this 'crashing out' point. ill try a seed next time to get one crystal. sounds effective.
also, when left to set the oil and dirt falls to the bottom first. i will let it sit until this happens then pour the naptha to a separate container, leaving the oil behind. the oil sticks to the bottom so well it will separate easily. sound good?




the first a/b i observed did not use a defat step. solvent was added to the brown soup after washing the bark with acid, and converting to basic. so pulls were done to a brown soup. this was the most recent, in which this room temp precip was done.
the defat was left out in fear of losing weight, but now i know most that weight is not spice

im observing a new a/b with 350g mimosa. currently in the first acid soak. cant wait for it to produce rich, one inch crystal be patient and do it all right, no short cuts this time.
so this is the third time for me. and it only gets cleaner every time.

P.S. the first time extraction, two years ago, was an stb,,,and the first two trips told me to make it "crystal clear"(those were the two words i remember from my first) like something was pushing for cleaning spice or im just a perfectionist.
