@_Aurelias congratulations!
I too have just successfully completed my first extraction with AA, using Cyb's Hybrid Salt A/B Tek, except utilizing xylene initially, backsalting and then pulling with naptha. I would consider my first two attempts with 50 grams of powdered bark a total failure, and most probably not because I didn't extract any of the spice, but because I just didn't know what to look for. My third attempt with 100 grams of bark has finally proved successful.
Some random thoughts below:
-I was expecting to see many clumps of crystals after the freeze precpipitation event, and although there were tiny specs visible in all of my attempts, it was assumed a failure the first two times. In reality, if I had just been patient enough to allow the evaporation a good 12-24 hours, the very slight film that encompassed these tiny specs would harden and scrape up into the marvelous wax seen on the razor blade in the first image below, weighing about 130mg. I was surprised what this very slight film that was almost invisible to the naked eye, scraped up into, and the resistance it provided against the razor blade was instantly recognizable. My conclusion, as far as AA goes using Cyb's tek, if there is no resistance felt when scraping, or the scraped up material is sandy/course/crystalline and not a dry amorphous substance, it's not dry enough and it will be impossible to compile much of it at all, unless there are huge deposits of it.
-Freeze precipitation clearly was working to some extent, but the end result was just 130mg after freeze precipitation from 100 grams of powder. I had evaporated the naptha considerably, but perhaps still not enough, or perhaps those who claim the FP should go for 48 hours are right, because the longest I ever performed was 16 hours (still learning patience). Regardless, I went the old barbaric route and evaporated the remnants of naptha from the freece precipitation event, and very quickly it started turning into the gooey goodness seen in the second image below. It looks at least 10 times more substantial than whatever the freece precipitation provided, I will guess about 1.5 grams, giving me a yield of about 1.6%, which is right in line with expectations. This is taking much longer to dry out though. A Re-x may be performed on this depending on its appearance compared to the FP yield.
-After pulling the xylene from the backsalt, some of the vinegar solution was inevitably taken with it. Since leaving that xylene in the jar, there is a small layer of vinegar solution at the bottom, which has since seemingly pulled an astronomical amount of alkaloids from the xylene. In fact, the xylene itself looks absolutely loaded with floating particulates. Likely these are just fats/impurities, and it would be safe to assume so given my yield seems to be in-line with expectations, but I will evaporate this xylene slowly over some days. I will then Re-x the leftovers using naptha and see what I'm left with, but I have a sneaky suspiscion there is a lot that wasn't pulled during the backsalt. In future, I will monitor the acid solution's PH level between subequent pulls to ensure it doesn't become too basified between pulls, assuming there is a considerable amount left in the xylene.
Happy days.
@Transform thanks for your help with my many questions
