I did this.
Took 32 inches of reduced bridgesii tea. About 200ml I think. Added 400ml of basified water, 120g lye. (I always add a little extra lye cuz the stuff sticks to my glass cup) Of course, you gotta add lye slowly, with gloves and eye wear yada yada.
Swirl this a lot. Shaking caused an emulsion even in a tea with little sediment. Add solvent, I used toluene. Just add enough to pull, 2 inch layer worked for me. Swirl, set, repeat many times. Let settle and separate an hour or two. When you pull your solvent, it's good to set the jar of solvent, into warm water, to help any last bits of water to escape from the solvent. Add your acid of choice, swirl and settle, takes just a minute, and remove you aqua acid layer. This is best done in a thinner cylinder jar, ime, so that the water is easier to pull. If you just have regular jars though just angle the water to a corner to get the most.
Umm, tek? If I were to do another extraction, I'd do it much the same, on a larger scale. Say 8-16 feet, or about 20lbs or more fresh cut. Cut up in chunks, simmer 2 hours, strain, repeat, 3rd pull I'd boil the shit out of it. Filter once or twice, nothing excessive, metal strainer what I used. Take 3 pulls, combine, and reduce, or you can reduce as you go if you short on pots like me.
I'd reduce to a liter. Add a liter of basified water. Alternately you could add couple hundred mls to a couple jars, just break it down. Whatever you want. Add your solvent, shake, settle, pull, add acid water to solvent, about 1/5 the amount of solvent. Pull your water and allow it to evaporate SLOWLY.
I made a thread in Cacti - Extracting from tea, about this,
here, basically if you know what's going on it's super fucking easy. Make tea, then a STB like w/ mimosa, + 1 step for the acid pull, be careful
