Recently completed the first ACRB extraction using Cyb's Hybrid ATB 'Salt' Tek with good results (about 1 g. yield of tiny crystals, goo, and ???). Had a case of "extraction interruptus", and was only able to perform 2 pulls before having to let the mixing jar sit overnight (in the cooling down warm water bath) before performing 3 more pulls the following day. Naptha was saved from the first day's pulls and used in the pulls on day 2.

The result was mostly crystals and goo (brownish) from day one, and a smaller amount of crystals and a more solid goo (pan was put to dry in front of a cool fan for longer on day 2) that produced this substance when scraped up with a razor blade:



What exactly is that stuff - just another spice format? It looks like wood shavings, but is very sticky and can be rolled up in a ball, almost like a soft caramel.

The naptha left over from all of the pulls looked like this:



Is that milky white precipitate product? I intend to use this naptha for the next extraction - does that make sense? Thanks for the insights!

As long as you were careful not to contaminate the pulls with soup sludge then yes that precipitate is NMT/DMT , NMT will stop crystallization of DMT and vice versa and depending on the NMT/DMT ratio you will get anything from yellow crystals to a tan goo.
Looks good to me anyway, time to prepare yourself for the unknown

Thanks for the insights, DreaMTripper!

I also get a combination white fluff and the off white waxy kinda stuff when using ACRB. Did you mix the to types together? Ive been keeping mine seperate and just wondering what other do?

I didn't mix them (much). I separated the fluffy crystals from the goo the best I could - mainly for aesthetics, I suppose ...
