Hey just did an extraction mostly followed thick lights tek (someone already posted the link) A couple of hints I can give you. I used powdered bark. But did my acid boils (the consenses is that vinegar is tge best acid to use with acrb) with the bark inside of a 25 micro silkscreen bag and I got almost 0 plant matter in my soup. I just kept boiling this bag over and over like I was making tea. I used my ph meter to make sure that my acid boils were 4.0 and when I basified I used lye to raise it to 13.5. I reduced my acid boils on the stove a lot before I basified. Probably reduced 3 gallons of acid soup to around 3 quarts (so it would fit in a 1 gallon wine jug) . Didnt measure the vinegar or lye just went by ph. I had no emulsions at all no matter how hard I shook the naphtha soup mix. If you have any other questions ill answer as best I can. Im not an expert but my first try I got 1.5 grams of white crystals and about 1.5 grams of goo from 250 grams of rootbark. Another thing I started trying to cryalsize in jars but it was was to hard to get it out so I switched to a large pyrex bowl. Sourced rootbark from acacia confusa grown in HI so doesnt even go through customs.
