About the Amidol not dissolving, I noticed that Michael Smith had that happen at his recent workshop, although the stuff worked just fine. He noted that it never really dissolves for him but it doesn't affect anything.
Mine dissolves just fine. I have no idea what the difference is, although as I mentioned at the very top of this thread my stuff has a VERY different consistency than Michael's or Formulary's. I bought some from Formulary just to see if it would be different, and it looks completely different and dissolves differently, but the prints are exactly the same.
