I recently did an A/B extraction using vinegar, lye, and mhrb and got pure white crystals on the sides of my jar that i freeze precipitated in, and then yellowish stuff on the bottom.
I did three acid washes with ph 3 vinegar water solution. The first two lasted about 75 minutes, and the last one was 4 hours. Then i basified and did four pulls and used way too much naptha (my first extraction.) Then i evaporated my naptha to about 75 ml and freeze precipitated and the yellow showed up on the bottom and the white on the sides and floating around in the solution.

Does anybody know what may have caused this, I filtered really good, and decanted too.

I do STB and after all is said and done I've got more of an ivory/yellowish spice. Most of the time right out of freeze precip there's white crystals like sugar, with a shimmer to them.

After it air evaps it starts getting a yellowish tint to it. I assume this is from oxidation and doesn't have anything really to do with the method of extraction. I always sample after everything is dried and it's absolutely good stuff. Color to me is aesthetic.

You can always re-crystallize or do the sodium carbonate wash if you're going for a certain look. I personally don't care if it gets a yellow tint to it. It's better for me to leave it and retain the yield then to waste it for a certain look. It's bark anyway, how impure can it really be?

If you're doing your pulls right with no gunk being pulled into your solvent and evapping/freeze precipping correctly your going to end up with amazing stuff!!


BTW> How is the A/B extractions yield for you typically?

amazing. grand. crazy. awesome. potent. strong. mind blowing stuff.

i've freeze precipitated a few yellow crystals with naphtha via q21q21's. That's the only tek I've ever used, never any STB's, but I read an older thread in which q21q21 found that a smallish amount of the "jungle" fraction is pulled with naphtha...

it's only ever been like 2 crystals in a single extraction, but I have noticed a yellowish tint to the used naphtha if i pre-heat it and reuse a few times...

^^ Hell yes.

I find it funny how sort of "scary" it feels at first then I just feel myself giggling when the infinite space opens up behind my eyelids and my carrier wave comes in!

SO SCARY! Then just like, wait a second, this is so familiar, and beautiful. and fun. and I LOVE IT! But when sober, STRONG anxiety about the blast off.

I tried the white stuff and blasted off. I think the yellow is safe too

So by now you already know you have some vape worthy spice there indeed friend! Welcome to the world of hyperspace.

I've pulled spice ranging from close to white, through yellow and recently I pulled something with the colour and consistency of milk chocolate. In my experience it all does the same thing when vaped, as long as you are confident you are using clean chems and haven't pulled any of the mimosa soup then you should be grand. Colour really doesn't make much difference IME.

yeah, i'm pretty satisfied with the results, what gets me is why the bottom of the beaker was yellowish but the sides were white. Overall I think it was a good first extraction, and i'm very satisfied with the results.

What happened was you got a mini recrystalization going in the naptha when you freeze precipitated it.
The impurities are less soluble in the naptha than the DMT, so they preciped first (along with some DMT) and settled to the bottom of the jar.
Nothing to worry about. If you are, just recrystalize the yellow to get white alks.

I thought that may be my problem too because I never seem to get hard crystals but a very fine, sticky, wet-yet-dry substance when its at the scraping stage. I know a re-x would make it more white, and there's plenty of tek's to change it into glass, but why do that when you've got excellent product to begin with?

A little yellow never hurt anyone!

Trying to get some pics from my phone....

This is what I usually end up with.

And I just got through scraping last nights batch and got this:



So I'm pretty sure open air evap is turning my stuff yellow. I tested it last night and can confirm its splendor and glory. NO gunk is being pulled with the solvent at all, I'm sooooo careful.

Is this how yellow your yield is?

All the pics are different pulls/batches. I also think another poster said you get more yellow when re-using naphtha, which I continually do!

kind of, i posted a picture

Its hard to tell on the left side... It still looks wet.


How about after it dries and you chopped it up, got a pic of it?

The yellowish tint is just fine. There are a couple factors that I know of that can have an impact on your color.

length of time you allow the naphtha to sit in the basified solution is one.

temperature of the basified solution and or the naphtha you are using to pull is, IME, the one factor that has the biggest impact on color. I know allot of people tend to heat or warm up their jars in a bath or with a heating pad. This may or may not help the naphtha absorb the DMT from the basic solution. It does facilitate the tranfer of colors/dyes, fats/oils in the bark and possibly other alkaloids into the naphtha.

I dont believe the yellow is from oxidization. I could be wrong I havent read anything proving that.

I dont believe anyone can tell the difference between yellow and white in the effects. I have heard one or two out there say they can. I would love to do a blind test with those individuals and prove em wrong. I have personally done many blind tests and I have hundreds and hundreds of voyages, I cant tell the difference in the effects. I can notice a diference in taste if vaping spice in the crystal form through a GVG.

I have made different batches of changa using white spice and waxy orange jungle spice. I cannot tell the difference in effects or in taste.

The important thing is to keep the naphtha you pull contam free. In other words keep the basic sludge out of the naphtha! If you do this your spice will be just fine.

@EzekielCain the yellow spice you have there looks to be some beautiful looking stuff. I would say that it is easily as potent as any white stuff that anyone else on the nexus pulls.

In closing, I would like to say that, IMO, you should NOT get all hung up on the color of your spice. You can re-x and do carbonate washes til the cows come home and your color may get lighter but your ptency WILL NOT INCREASE! So why bother? lol if anything your going to lose some every time you wash it or re-x it.

my 2 cents

IH

@Ice: it is friend, it is. I was giggling like a school girl when I tried the littlest amount. Its so ridiculously potent its not even funny.

The little jar has just shy of 800mg. I'm going to do a re-x on most of it since I've got DMT coming out of my ears now with daily yields.

And maybe its not oxidation afterall. I don't do heated pulls or hot water baths, and I leave my solvent standing a minimum of 24 hours after 2 agitations.

I'm with you about color.... Thats in the eye of the beholder, cuz I guarantee you'll be launching into hyperspace off my yellow goodies!
