hey swim has about 7 g's of really yellow crystal from a nomans stb extract .swim has done several recrystalls on this using heptane but the oils keep getting in. its getting cleaner slowly but there's gotta be a better way to do the whole batch without filling my freezer full of shotglasses. any ideas ? thanks you guys rock

explain how are SWIY is making the recrystallization.. doesnt make too much sense that SWIY has done several times and its not much much better

3 well done recrystallizations can leave brown crystals as pure white

swim boils water puts and puts 1 g of yellow crystal into a shot glass with 25 ml of heptane. the he waits for the crystal to melt while stirring with a toothpick till its all dissolved and there's a puddle of yellow goo on the bottom then i take the ol turkey baster and suck out the heptane into a clean s shotglass and let cool slowly then freeze precip. there's always a yellow ring around the top of the shotglass and the crystals in the bottom are a little whiter but nothing that great. i think i just got oily bark. dunno

Doing a A/B extraction from yellow crystals worked fine for my friend. Expect a loss of yield however( around 10%).

Maybe using acetone on dried basified stuff instead of freeze precipe would work also.

mmmk but how would one do an a/b after he's already got crystals. is that a little excessive?

anyone??????

You must heat the splice solvent filter then allow it to cool until the yellow crap goes to the bottom. Then you can seperate solvent from the goo there ate variousb was to do this.
Or it you are getting a slag pellet on bottom with cleaner spice on top you can use a lighted dental pick $10 US any drug store. you can then use a light brush and lighted dental pick to remove clean spice from slag pellet. repete until clean 20 or 30mg of activated charcole pet store. Just use a very small amount of it will suck up you spice. It is very effective in removing colored impurties from solutions. You can find the procedures from any basic organic chemestry book. It will cover extractions and xtal growing proceedures.
Good Luck

M.V.

just melt it all back into naptha or solvent of choice
when still warm put in frezzer any contanier
wait 10 min the heavey oils will drop to the bottom
poor of into new container leaving yellow
put new into frezzer for snow glob or leave out for crystals
reheat yellow with new solvant and reppeat till happy you got all dmt out
youll get most back after first round

Maybe a bit 'excessive' in regard of the yield loss, but not about the quality. A friend had 1.4 g of very brown stuff. Not yellow, really brown, looking like cane sugar. He also had 100 mg of very greenish spice from chaliponga (pretty unsmokable in that state).
He mixed the whole and disolved it in 100 ml aciditic water (hcl), measuring PH was not needed, he just added hcl drop by drop until all spice is disolved. Liquid was filtered, then basified until no more precipitate forms (again no need to measure PH, it's become obvious when nothing new happens - it was however checked at PH 11.5-12).
50 ml of cold naphta was added, shaked a lot. It was very interresting to see that some brown things were forming at the surface of the basified water, between the two laters. My friend carefully took the clear naphta layer without the brown layer.
Freeze preciped and yielded 930 mg of very nice, fluffy almost white spice. So indeed a big loss of yield but the result will be very enjoyable while smoking the brown stuff was very harsh...

another GREAT way to get the yellow out is the FASA method...put one gram of spice in 50ml of acetone and 309mg of fumaric acid in another 50ml of acetone...make sure they everything is taken up by the acetone...and then mix the two together...it will cloud and then the crystals will drop out before your eyes...wait a bit..and then pour off the acetone and then scoop out your still wet from acetone crystals...put them on a flat surface and let them dry...

you will have super pure dmt fumarate which you can then convert back to the free base with a gram and a half of sodium carbonate...ad a bit of water...mix for ten minutes..and then let it dry..and then throw it in some acetone 50 ml of acetone...stir and pour of acetone leaving behind the solids...evaporate..to get really pure dmt...

what SWIM would do then is put that spice in some heptane or something...and the freeze precipitate it..so you end up with snow white crystals...(not sure what the crystals look like from evapped acetone)

Is there a comprehensive Recrystallization Tek and Room Temp Evaporation Tek I can use as a reference?
