No, I don't think the product of your STB contains much DMT. I think the DMT is probably still stuck in the bark.

For changa, the best way to go about it is to dissolve DMT in a minimal volume of a quickly-evaporating solvent (everclear, 99% isopropyl alcohol, acetone), put the leaf matter in a small glass or ceramic bowl, pour the DMT-containing liquid over the leaf matter, and let it evaporate.

Awesome! I shall try that. What kind of leaf matter is easily obtainable, and makes for a pleasant experience? Do I heat the leaf, or light it like weed?

You can find everything you need to know about changa/ enhanced leaf:
here,
and here,
and elsewhere on The Nexus.

The extract you have got cant have much DMT content as previous members pointed out.
I have done Acacia Confusa root bark extraction real lately and when i put a small piece like a matchhead in my glass pipe (made out of an test-tube) and warm it with a lighter, just a little of the smoke get dramatical results.

I can recomend Cyb's & CTM's "Max Ion" tek.
I get very good results with this tek however when adding the salt solution something precipitates (who obvously isn't DMT) and this precipitate is really a bitch to filter out even with vacuum filter equipment.

Try a tek with a small amount of bark (50 grams) and dont use large amount of the bark until you got a good working procedure.
Pick a tek with acidification step and preferably a defat step included.
I get large amounts of stuff removed in the defat step so with acacia it's probably needed.

If you have a small propane torch (larger than a lighter) you can make a simple glass pipe out of a test tube.
I attatched a hose to the end of the test tube so i could blow in the hose without having to put my face close to the heat.
I then warmed the end of the testtube in the propane torch until it started to deform and then blow hard in the hose.
The result is a round bubble at the end of the test tube.
If one now put the bubble directly in the propane torch and blow simutaneously in the hose a hole is formed in the bubble.
Then carefully smooth the edges of the glass on the propane flame and you have a working glass pipe.
It kind of looks like a crackpipe though.
But it works.
Look up the procedure of the glasspipe on youtube before trying so you understand completely before trying as glassblowing can be dangerous.

Goodluck

Grower, that is brilliant! I have plenty of test tubes, as well as all the other lab equipment I could need, so I can do that. After all, this is a lab. I have about 9.9 kilos of ACRB left to play with, so I'll try running all four of the methods at the same time. Before, I thought it would definitely take at least 100 mg per use, otherwise, I wouldn't have bought so much of it. This will probably end up with me having a couple years supply

I just gotta do it at night, when nobody is there. Thankfully, I've got unrestricted access to all equipment, non-scheduled chemicals, and glassware/plasticware. I'll just report the test tube as broken and disposed of.

When salting the solution, do you know what exactly it is that falls out? That sounds like a salting out procedure.

Remember, I'm still learning here. Don't take anything I say in a way of me being some kind of professional in this.

Please read the Attitude page.
The Nexus does not condone extraction sites where the owner is unaware. This can lead to detrimental situations.

Also Machine here is a better way of vaping than the conduction method that you have used.

You really dodged a bullet using way too much. You need to do a little more reading before continuing IMO.

Don't worry, I own the extraction site. I'm an entrepreneur. Its the employees that don't get to know. Its just a lab with a couple college chemists. Its simply an R&D company, with only three projects. I may not be the most knowledgeable chemist out there, but I have run businesses before. The lab's original purpose was actually for me to study, but while coming across ideas, I decided to test them. The expenses are written off, we can try to get grants, and we work for nearly no pay. Really, just to hang out and learn, while trying to develop.

Yes, I must have dodged a bullet. I won't deny that. I did quite a bit of reading before, I just never encountered anyone that knew this much about it, I guess.

What exactly is it that makes the machine so effective? Isn't it still heated by conduction, just with the heat kept in the steel wool?

The spice is vaporised via convection...basically hot air (not flame) is passed over the steel ribbon. The spice melts at low temps (50 deg or so) and tends to run away...the ribbon is there to catch it long enough to be vaped (160 deg).

With conduction the spice will just pool, bubble and burn...burning spice is quite horrible to ingest and produces nasty results or no results at all.

Ah, that does make sense. In fact, that gives me an idea. I have a kind of pipe that is a small glass tube, connected to a bigger glass tube. The smaller one can be slid out easily. Could I just put some steel wool into one of the ends of the small one, and use that as a Machine?

I also know the testtube glass pipe isn't really an good way of delivering the spice, but it do work if a good vaporization device isn't at hand.
One can make an insert in the glass pipe with some copper wool or similar and make the heating convection instead of conduction.
Then it becomes something like a machine setup.
Reading the threads about DIY macines is very good and informative.

I still haven't figured out what the stuff precipitating when i add the salt is.
As it still is in the acidic stage so it shouldn't be anything active.
It's just so hard to filter out even with vacuum filtration.
I guess the particles are just the right size to clog up the filters very quickly.

One can let the solution stand for some time and this precipitate will fall to the bottom but it take quite a while and some active stuff will probably get stuck in this gooey stuff.
