IPA and ethanol will pull slightly different impurity profiles, I guess. And, rather than guessing, that solid material needs definitive analysis. It reminds me rather a lot of calcium acetate just from visual appearance.So the ethanol 96 made a slightly different mescaline carbonate than the iso99 I made in the past. Was a much white grain in the past
I’ll test solubility in a few days
You did mention having treated one or other of your extractions with lime higher up this page. What salt form was the "1.9 grams of dirty Kash extract"? The original tek mentions HCl for salting, but I can imagine you using acetic instead (which is fine).
