Hey, sorry for the delayed response, work's been a lot, and for some reason I wasn't notified of the new activity.

There is an extremely fine precipitate in my solvent. It does not look like very much. It's fine enough that I don't think the coffee filters I have on hand will catch much of it. It pretty easily goes back into suspension when the solvent is poured, which is why I was considering trying to force it to re-dissolve in the solvent with saturated Na2CO3, and then either concentrate it and salt it out after that, or reuse the solvent so it can fall out after extracting from fresh material. I'm leaning toward the latter.

The former goo does seem crystalline now, and definitely does not taste like citric acid. This is my first time anywhere near mescaline, so I don't really have a frame of reference on flavor, but it seems to fit the description I've read in this thread. Slightly bitter and slightly sour.

I haven't had much time over the last few days, so I threw the used solvent in the freezer--no ice formation at all. I'm not too surprised at that, considering the fact that I used way too much (about double) solvent this time. Admittedly, I was thrown off by the description of the quantity of solvent as "a couple fingers" worth. Might be worth removing that from the tek.
