Hi fellow travelers, I am sorry to post without giving out any of my knowledge or contributing else where, but I ran into an issue with my first extraction. And I wanted to go over every possible reason for my low yields, because I am not a rich man and do not want to waste bark, if I don't have to that is. Anyways, I followed cyb's hybrid ATB salt tek. 50 grams of ACRB powder was put in a mixing jar/bottle, and 200 mL purified water was brought to just boiling point with 50-60 mL of white vinegar. The acid solution was then added to the mixing jar/bottle, and left to soak in a heat bath for an hour and a half(shaking/mixing occasionally to prevent settling) . 30g of deionized salt was dissolved into 100-150 mL of purified water. The saturated solution was then added to the mixing jar/jug. Then 50g of caustic soda was added to 200mL of cold purified water,carefully mixing until dissolved, then added to the mixing jar/jug. Topped up with another 140mL of purified water, then the mixing jar/bottle was left in a heat bath for 2 hours(shaking/mixing to prevent settling, careful to form no emulsion, although there was this foam/plant matter looking stuff on the top of the solution). Then 50-55 mL of warm naphtha was added, swishing the mixing jar/bottle in a "figure 8" motion for one minute, then left to settle. Repeated this process three more times, making four in total. Unfortunately, during the extraction of the naphtha, my turkey baster broke, so i had to slowly and patiently extract all 50mL of naphtha with an eye dropper into a pyrex dish. The extracted naphtha was of a yellow tinge. I read this means it is saturated, yellow is fine. The pyrex dish was wrapped in ceramic wrap, and put in the freezer for 14-16 hours. When i pulled it out and dumped the naphtha out in a storage container, the only thing that was left were a few yellow dots. I assumed this was the spice, and it is still drying. There was very little yield, even though it was one pull, I expected a little more. I was thinking maybe it was bad bark powder, or my freezer was not cold enough? But before i dispose of my bark and find a new vendor, I would like to hear the opinions of other who may have had this issue. Maybe i overlooked something? If you took the time to read this, thanks for hearing me out!

Was the naphtha cloudy when it came out of the freezer?

There are a lot of reasons why this could have been unsuccessful. Bad bark is one of them but I wouldn't make that assumption just yet. I'd hold onto everything until you find out where it went wrong.

The naphtha was indeed cloudy when it came out of the freezer, but still sort of a urine color to it. I scraped up the first batch, and i assume what is about .1-.2 of NMT because it is quite gooey. I have already started the second pull, taking my time. Added 50mL of warm naphtha, and and mixing/stirring and letting settle in a heat bath. Why do you think the majority of it was goo? Did the crystals crash out at room temp?

Did you weigh the goo? It's normally much heavier than you'd think & can dissolve/hold/keep alot of spice from crystallizing.
Keep pulling until you don't get anything then combine & clean up the oils.
There are alot of different cleanup methods you can use, dissolving in dry acetone & converting to fumarates may be the best option because it will leve oils & fats in the solvent & precipitate your spice.

I havn't busted into my acacia stash yet but i just used fasa, washing, & re-basing to turn a gooey, liquidy, impure full spectrum mhrb extract into clear crystal shards.

I did weigh the goo, and it was about just as i assumed. It has a reddish tint to it, I'm guessing because the powder itself was almost a maroon color. I will do as you said, thanks for the tips. But if it does not yield much more, can I assume the bark is of low quality and has a miniscule amount of dmt in it? I followed the tek to the dot, and it should have yielded a fair amount of crystals as well as a little oil. I read all plants are a little different, so this particular plant might be loaded with more useless fatty stuff, and less actual goodies?

And wow! Good job man, messing with this goo is no easy feat!

If the naphtha was still cloudy coming out of the freezer, it likely still has DMT in it. As I understand it, the DMT has a hard time crystallizing and freeze precipitating when there are plant fats and impurities in the NPS.

The other advice sounds good as well.

I have also experienced low yields with acacia in the past couple of weeks. I was using earthwalkers 100g tek. On my firts attempt i only managed to extract 0.2g from 100grams. Second time round I got a little more but still only around 0.5g. Just like yourself i followed the tek I was using to a t.

After 2 attempts with similar low yields i have came to the conclusion that i have low quality bark.

Today used a different tek then i did for my last 2 extractions.... I used the cybs hybrid salt tek just like you did.....my baking tray has just went in the freezer so i guess ill wait and see how it turns out in the morning.

Keep trying different approaches.
More pulls may be neccessary, maybe the first few grabbed alot of fats & oils & theres still spice trapped in solution.

The solvent issue mentioned above may also be a problem.
Try evapping if freeze precip isn't working & if the yeilds are better clean up with different solvent.

The bark may be low in dmt, but i'd work more on it & see if yoi can't get anything out before blaming alkaloid content.
In the event it is the bark, try new sources. Often one place may have a low yeilding batch while somewhere else may have stuff harvested during a different season or from older trees, etc. with higher yeilds.

My personal experience has lead me to believe that the temperture of the water used with the ACRB is the most important part of the extraction process. Maybe try boiling the bark for 1 hour, filter and continue from there

! This just occured to me.
Your bark was pre-powdered. It may just be that you need to use more water.
Note that in nomans tek it says that for finer powdered bark you may need to use 2x the water.
This may be noted in cybs tek as well i'm not sure, but it's another possiblity.

Thank you for the advice guys! I pulled from it 4 times, and the forth pull pulled nothing, so i will add some more lye and try another pull, and if nothing is yielded i will consider it depleted. The naphtha I saved from all the pulls looks as though there are little particles floating around, so maybe i will evap that and see what happens. If that really is spice, why was it not separating from the naptha during precipitation? I still have 100g of bark powder left, so i will attempt Earthwalker's tek.

And what does boiling the bark accomplish?

Boiling the bark when the solution is acidified helps to extract the dmt into the solution.

I appreciate the advice travelers. I have a question regarding earthwalker's tek. If i were to want to do the acid boil, should i just interchange this with his first step? Or boil the bark, then still follow the tek to the t.?

Earthwalker's first step: Step 1
Measure out 100g of powdered ACRB , place this in a 2 litre bottle
( preferably ) with a thin neck then add 500ml water mix gently and make it a nice consistancy with no lumps of bark , you want it to be able to slosh from one end to the other .............then add you're preferred acid the easiest to procure is normal white vinegar and mix at least 50-60ml to the bark water mix and this will give you the acquired ph ........................ Then allow this to sit for at least 1-1/2 hours in a heat bath and give it a swirl around gently every 10-15 mins
Be careful not to cause an emulsion

I would say don't evaporate your naphtha, do a mini A/B on it and clean up with acetone and fumaric acid. Sodium carbonate as a base.

The boiling would be in place of the heat bath that I bolded above. You can follow the rest of the tek or (IF you just want to quickly find out if there's anything left) you can take the first pulls and evap them and see what you end up with. Some people don't like to evaporate naphtha though.

I always get good yields with the Thick Light tek from acrb. Tried the others but this worked best for me. Q21q21 d-limo tek worked too. I know a lot of people have great yields with others but I had issues like yours. The freeze thaw cycles and heat did the trick for me even without the rock salt step. I usually add salt 2nd pull. I also do a sodium carb wash of the saturated naptha right after pulling.

You say you've had good results with q21q21 skoobysnax?

I've been looking around for info on others using drytek for acacia & havn't seen much.
I'd like to try it but don't want to waste bark if yeilds aren't great.

Hi concombres,

And thanks to everyone else who put in their input! I appreciate you being positive to a new extractor and taking the time to share some knowledge.
