I had some jugs that I decided to squeeze the rest of the magic out of, and the naptha that I pulled up was brownish yellow after the layers separated. I did a recrystallization 3 times before I put it in the freezer, but the naptha and crystals are still piss yellow. I typically re-use my naptha, so I'm wondering if it's okay to use it in future extractions, though I doubt I will so that I can get purer product. I used the standard Noman's tek that I've done many times before, but I had never extracted from mimosa/lye mix that had been sitting around. I'm also wondering if it's okay to smoke once it's dry.
