My First Experience With The Infamous Yellow Goo (STB extraction)

[Sil]

Hey everyone!

I just wanted to share my knowledge and experience so far in a particular matter which many find annoying.... the dreaded Yellow Goo! *Everyone hears a woman shrieking in the distance*

I had done my usual process:

40g MHRB (Brazilian)
60g NaOH
5 15ml - 20ml Naphtha pulls into decanting jar for later transfer into pie dish

I decanted and put golden yellow naphtha into pie dish making sure to keep out any of the brown muck as I always do, and placed in front of a fan set on high (this usually produces a 'sandy' type yellow spice for me ('The Spice Melange') ) and waited almost an hour until completely dry. Of course as I previously mentioned, I was presented with the "goo challenge" so here's what I did...

First, I scraped up what I could and spread it about the pie dish and set it in front of the fan on low speed... this allowed it to dry fairly quickly as I kept mixing here and there, but not constantly. The goo turned into a maple golden color, kinda like the color of maple frosting on a maple bar and hardened into a slightly waxy substance. I chopped it up as best as I could and placed in a vial. I tested a bit of it last night, very nice experience. No anxiety, and very "humble".

On my fifth pull, I did heat my mimosa soup mason jar in a hot water bath WITH the naphtha in it and let sit for an hour, mixing here and there. I usually do my pulls as fast as I can but wanted to test this method to see what would happen. I think this may have attributed to the goo.

I have a couple hypothesis about the formation of this goo in my experience and they are the following:

* On my fifth pull, I broke away from my usual process, and let mimosa soup with naphtha added sit for an hour in hot water bath while intermittently mixing. I believe this may have contributed.

* During evap, I left the fan on high, but the detail I left out earlier is I usually move the dish around so as the let the naphtha evap more quickly. I did not do that this time, I just let it sit and evap. I believe this may have also contributed, but this is just a hypothesis at this point.

* This last batch is what was left over from my first pound of MHRB. It has sat in a drawer in a non-air tight paper bag. I believe oxidation may have been a factor here as well, but not sure.

Just wanted to share this with everyone who is taking notes.

Thoughts?

i have yet to do my first extraction but i have about 500g that im planning to do small batches w/ to learn. yellow goo is bad i take it? is it like MHRB's version of Syrian Rue & Harmala Red?

It's not necessarily bad persay, it can be purified further for a cleaner product.

It is definitely an annoyance though for sure.

The good news though is that DMT N-Oxide can be converted into Freebase DMT.

That oxide conversion won't help, because it isn't oxide. If it's yellow when you pull it, then it is contaminated with oils and other psychedelic alkaloids... if it's white when you pull it and then turns yellow, it's oxidized.

You can just re-x in acetone for safety and smoke it up, convert it to fumarate and go from there, or whatever. If you don't like the yellow, go easier on the heat and longer on the acid next time. Simple as that.

You're using quite a lot of Lye in your mix.
I use 30g per 50g of bark. in around 600ml Water.

Also I use around 40ml Nap per pull.

25ml will saturate quickly and is hard to separate a thin layer.

Heat baths will make the nap more yellow (pulls more oils).

STB's tend to be more yellow anyway.

I have taken to Re-xing the gooey mix/xtals and am getting a much cleaner product.

If you are unsure of the re-x process...here is my method:

Put 20/30ml Solvent in small jam jar.
Boil water in a pan and sit a sieve on top (stops the manic bubbling)
Put jar in water (within the sieve) (just need water level 1/4 way up jar)
Rest the lid on the jar (do not screw shut...the pressure build up is extreme and may explode...not good!)
Bubble away for 5 mins (solvent with get nice and hot)
Put goo/mix in a small glass/shot glass
Turn off heat and Use Gloves to retrieve the jar...Pour hot solvent over the goo in the small glass
It will dissolve but sometimes needs to place the glass in the heat bath (not boiling) and stir for a while (I use an eyedropper to stir)
Leave for 5 mins
Take out of bath and notice the separation of oils and other gunk.
Carefully decant/pour/turkey baste the solvent into another clean glass (best to use a wide based glass (easier to scrape later). Careful not to get any oil/gunk.
The solvent may still be yellowish.
Leave to cool with tin foil as a lid (stops dust and hairs getting in) Room temp is fine (bout 1/2 hour.
Then put the glass and foil lid in the freezer and leave undisturbed for 18 hours minimum.
Take out and pour out the solvent (keep for further pulls).
Marvel at the crusty layer of much cleaner crystals coating the glass.
Now fan dry for 1/2 hour before scraping.
If you don't have a fan it may take a least a day to evap all the solvent. (Patience)

That's it...sounds a bit scary if its your 1st time but it's so easy once you've done it.

Hope this help you and others.

Thanks everyone for your thoughts and input!

Hiyo Quicksilver,
Thank you for pointing that out!

I would consider a new approach with your pulls for one.

Evapping is fine I tend to do it after most all of the goodness has been pulled from your bark.

I would consider combining all of your pulls into one container, allow the combined container to of Naphtha to evap down and become saturated enough to freeze precipitate.

You are going to get a cleaner product that way and you will be able to guage better how much goodness remains in your bark to pull.

Once there is no more crystalline like spice precipitating out of your pulled naphtha you know that you have exhaustd your bark. Then I would evap what used naphtha you have left. The gooey resultant "Jungle Spice" works great for changa.

Make that Naphtha go a long way. Dont be in a hurry to evap and vape. Patience, patience, patience.

Practice makes perfect, you'll get better at it. Refine your technique a bit and you will
see better results.

5 pulls is quite a bit on 40mg. I imagine it was pretty exhuasted after 3 pulls.

Keep it up brother, It'll get better.

Ice House,

Thanks for the tips man! I will admit I have been disappointed by freeze precip, but I have honestly only tried it once so far and have stayed away from it due to the fact it seemed like it took so much away.

You are right about the pulls. Usually 5 ensures that i get everything possible out. The advantage is that I am getting the most out of the bark, however, the disadvantage that I don't like, which you pointed out, is I am wasting a lot of naphtha.

I really don't mind yellow spice, in fact I actually kind of prefer it! The goo kind of threw me off though, and I honestly was expecting to get it at some point, just wasn't sure when. Glad it happened sooner than later so I can add my learning experiences!

I will definitely try out your tips here in future extractions (waiting on more MHRB at the moment. ) and let you know what happens!

Also, as another thing I will work on, definitely am working on my "patience" issue. I will say that I am a lot better now than I used to be thanks to these extractions! Rushing these things always leads to disaster if not careful!

you guys are lucky i keep ending up with yellow goo off a STB extraction of acacia confusa

Interesting.
I extracted from 120g MHRB in a 50g followed by a 70g batch.

The 70g was extracted using heated naphtha for every pull & I ended up with a fair amount of sticky crystals plus a dollop of goo. I also used a touch more naphtha than the 1st (50g) "batch".
I'm thinking the combination was probably not the best idea. The 50g batch crystallised quite well, although I decided to re-x the more yellow & sticky crystals.
