OK, so I'm pretty happy now because I think I've finally witnessed pure white fb bufo for the first time and it's been an interesting journey getting there... I have not tested it yet, but I'll tell you how SWIM got it and some observations made...
First I had 60g+ seeds from brazil/maya, SWIM toasted these seeds using his volcano on max, I think this stage could be just done in the oven, I don't think the volcano really adds anything, but I will let you know next time when I just do it in the oven... the main thing I noticed with the toasting is that it really helps with the grinding of the seeds, I've always done this with a coffee grinder, but with the toasted seeds I found I could easily grind them into a fine orange power using a pestle and mortar, I had trouble doing this with untoasted seeds. I did a side by side test with finely ground and less finely ground and amazingly, the fine ground power pulled over 10X more alkaloids. I really think this is a key mistake, the seeds really need to be dust.
SWIM freebased the ground seeds thoroughly with a bit of water, and I let it dry over 3 days, SWIM reground the powder after freebasing because I found it was holding a lot of water in clumps, by the end I was pulling from a dry finely ground greyish powder. From here did 3 acetone pulls, then FASA'd, the FASA'd acetone dropped most of it's contents in the first 2 hrs, but would continue to drop over 3 days... to yield 2.1gr of orange fumarate powder..... SWIM then fbased using s.carbonate, pulled from that using ISO, evapped into the usual brown goo, though this time it had a frosty, jungle fumarate quality....
From here SWIM began some MEK:naptha experiments and found that it was possible to just cover the goo in naptha then add MEK by 1ml increments I began with 20ml naptha, 4ml MEK and SWIM used a spoon to manipulate the goo, once it felt like it was breaking down the solvent takes on a slight yellow tint... then cotten filtered twice to get rid of yellow oils, then screwed me first time, the filtering is important because the yellow crap is hard to notice... evapped to leave a thin layer of white frosting on the dish, scrapped up into an off white dryish powder... looked very much like stb dmt....
I have one problem which puzzles me and it's that the white powder when scrapped up seemed to melt softly just like the black goo does, perhaps this is a slight residual.
