Have you tried the whole progressive toasting thing where you burn it, then filter out the goods more than once?
If so what's the weight-loss : purity you can expect on the second toasting compared to the first?
Also have you tried toasting before the initial limonene wash?
I'm in the process of doing it now.
I toasted the seeds @ 350F degrees for 30 minutes after they stopped jumping.
I pre-washed the ground seeds in acetone, using THP
before basifying & got a whole lot of dark yellow colored acetone out of it.
I did the rest of the extraction, doing one D-Limo wash, then dried it out & toasted the precipitate @ 350 for 30 minutes,
before scraping it up.
I let the dish cool, scraped up the burnt-black extract & dissolved it in acetone & filtered out the solids, then filtered the liquid 2 more times before evaporating & scraping up the drier, cleaner extract.
I then did another D-Limo wash, dried it, scraped it up, dissolved the
darker powder (??) in acetone for filtering & I'm waiting for it to evap right now.
When its finished drying, I'm not sure if I want to do the whole toasting/filtering process on it a 2nd time, or just try smoking a little, it's really pretty clean already.
Notes:
**When I did the acetone pre-wash, I was in a bit of a hurry, & I didn't have a whole lot of acetone either, so I only washed it 2 times, pouring 200ml of acetone through THP 5 times, each.
To be honest, I have not really noticed any difference in the amount of impurities or stickiness of the extract throughout the process. However, it did clean out a lot of yellow stuff. to make sure there was no Bufo pulled out with it, I poured some FASA into it & nothing at all precipitated!!
So I think I'll do it again next time, but I'll use a lot more acetone & keep washing it until the color starts getting lighter in color.
**A lot of stuff was burned out of the extract during the 2nd toasting. It pretty much cut my yield in half, after filtering the burnt solids out & doing a 2nd D-Limo wash on it!! That is just fine with me though, as long as it's
crap being burnt off & not Bufo & that is what seems to be going on.
I attached some pics of the first D-Limo boil I did for those new to the process to check out.
I numbered them, so they are in chronological order.
I'll add a pic of the cleaned extract to, after its finished drying & I scrape it up.
Cheers!
