I have made sodium bicarbonate wash few days ago on my 2 pulls. but when i did freeze precipitation no crystals appeared after freezing for 3 days. Today i took another pull and put it in freezer and i can see the white stuff after 3 hours. Is it possible the SC wash damaged the stuff or have any ideas? I let it evaporate a bit and then will try to freeze again i guess. If you got any suggestions i will be so happy

After freeze precipitation of some pulls i took a while ago i let the solvent evaporate for a while then i forgot it there without touching and it evaporated totally. I was so disappointed untill i opened the cloth i covered on the evap dish, then i saw ice clean 2-3mm diameter crystals in it. The cleanest thing i got untill now and no SC wash, no recrystalization nothing. Whats the trick with that? just not touching and letting it evap slowly grows crystals? if so i may dont bother doing freeze precipitation after now.

Dunno about 1, I never wash anything , ever.

As for 2, there is no problem completely evaporating the solvent, most do not due to the smell. If dont mind the smell and have no complaints, then hey go for it. Free precip is for people in apts that can open the window with a fan cause everyone could smell that shit.

I just put the half evaporated solvent which didnt give me any yield in freeze precipt. Lets see if i get anything from that today, i'll report. And from now on I will NEVER EVER bother with SC wash or any purification crap. Its already nice stuff i get from my extractions and i dont smoke it everyday. Let me die coz its not clean, but just not loose the pulls from 150gr stuff at total.

Purification crap?

Young man, I believe you are mistaken.

Why are you going to die?

Lol die i mean is not really dying ..i mean im just not that paranoid about the purification of the stuff coz its already light orange or totally white everytime. and if SC wash is such risky thing that can damage all the stuff yea its crap for me to be honest. why should i risk it? it was first pull from 100gr + first pull from 50 gr... so there was a lot of stuff in the solvent... hope it precipitates today so dont loose anything. and pls dont think its my first extraction or something, ive extracted more than 15 batches up to now.. and i have pretty experience about troubleshooting. But seing that huge pull didnt even give me a piece of yield made me crazy to be honest. First pulls are always the best and i wasted it i guess.

So if SC can do this i wonder what activated charcoal+IPA can do to my stuff.. remove half of it may be?
I got very clean crystals without even doing freeze precipt. So may be theres a very little trick about this evaporation. On my second question thats what i asked actually.

SC washes aren't really dangerous IMO, the water should be basic enough from the SC, and not much water should be used (it really is best to start with dH2O though). Very little DMT, if any at all, should migrate into the water. Lye will though!

Actually if i had transferred the water into another jar i could may be get it out later by NaOH. But i spiled it to the sink thats the problem lol probably ~200-300mg stuff gone eheheh but doesnt matter. Best experience i got out of it; next time im gonna try something new i dont spill the unwanted layer into the sink eheheh

I second that! Even when doing something exactly as you have done many times before it's good practice to keep your 'waste' material until you're sure that you've got the goods. I've had problems with the sodium carbonate wash myself (considerable loss of yield) and was sorry that I didn't keep the basified water

Having said that, I have also cleaned up some pretty sorry looking product and achieved pure sparkly glassy-clear crystals with the SC wash / Recrystalisation method.

First pull is always clear white crystals, decent to small yield, then the 2nd and 3rd pulls are great yields but can have a hint of yellow. Just my personal results.

just curious but wh at you say time, or heat allows for a greater yield in 2nd & 3rd pulls...does it provide more results if you soak for a day as opposed to an hour?

Actually it probably time. But I do not use heat, however at the start of the reaction, the water gets hot when you add the lye. Could be that it cools? I often take naptha from my collection jar, pour it into the first jar, shake , sit and pull right away.

I use a heat pad wrapped around my metal pot and it keeps it pretty warm,the 1st pullwas done that night the 2nd 3rd 4th pulls I gave them much longer to pull,like a day or two then 3 days.seems to help,Its like the deems sweats into the naptha.
This is the second pull from 1 pint size jar,pretty decent,the time helped i beleive.


the 2nd and 3rd pulls are looking yellow like this,i did one sodium carb wash on 3/4 of a gram and its slowly evaping in a fridge now,but heres the 2nd pull scraped up


Notice the color change from left to right,left is 1st pull and so on.

150G thats about 2 Rx's for me, so the quantity looks about what I get, however my first pull is much whiter than yours, I wonder again if I pull too fast after adding the bark as my first pull is usually the smallest, but most pure.
