So I was doing another extraction today (got a bit of time off at the moment)and wanted to see how far I could push Cyb/Earthwalkers tek. The aim was to put 250g into a 2Lt vessel and play with the water volumes at each step to see what kind of a yield I would get.

The only advice I would offer in doing this is allow the base to cool adequately in a separate container before adding it slowly and incrementally to your main mix. This will help regulate the exothermic reaction which could easily surpass any tolerance in glassware. I suspect the 'top up with water step' after adding lye in EW tech assists in reducing reaction temperatures.

Furthermore, I had completed 4 pulls yesterday and cleaned it up in a Mini A/B, which is freeze precipitating at the moment. It looks like a pretty high yield ~3.5 -/+ 250mg.

I knew there was a tiny bit left over so I went back out today and warmed up the soup and took two pulls, got maybe 200mg, or relatively nothing so I thought I'd pack up and get rid of the base mix.

The amateur chemist in me got thinking I wonder how much hydrochloric acid would be required to neutralize the mix so I started adding it in drop wise.

After about 30 seconds I saw what looked like balls of powder floating to the surface. I grabbed one from the top onto a tiny spatula and spread it around and couldn't figure out what it was.

So curiosity being what it is - is it more DMT? Got the pH meter out checked it at 11.37 - this was after about 10-15ml of hydrochloric acid. I warmed 50ml of naphtha put it in, mixed it around once and it saturated again like the very first pull.

Needless to say I'm pretty much going to start pulling on it again to see what more I can get from it in a separate side extraction.

I'm trying to think of why this has worked out, acidifying the ready to throw out alkaline solution = yielding a lot of product again? My understanding is the target pH for pulling freebase was 12-13.

Thoughts anyone? The initial PH was 12.92 in the initial pulls.

It's prolly salt (NaCl) because :

HCl + NaOH = NaCl + H2O
hydrochloric acid + lye = salt + water

Good man, I knew there would be an explanation. I'm not a chemist so this is exactly what I was after.

It did dissipate back into the mix on heat and I've done 4 good pulls since and they've been very saturated. I could go more but I'll run out of solvent soon.

Just doing a mini a/b on the 4 and I'll see what it yields.

Hey Trypt,

Was wondering what the 4 pulls from the near-exhausted bark yielded?
