I, too, am reading these posts with interest. At this point, salt prints and VDBs have been as far as I've gone with emulsion making, but I plan to do more.
Bruce, when I came back to photography several years ago, I decided that I did not want to get on the latest film/paper craze again. I picked Kodak Azo as the paper to learn to use. I figured it had been around more than 100-years, so it would probably continue to be available. We see how wrong I was. I'm using Ilford's paper now, and will use Lodima when it's available, but I want to know how to make my own emulsion, too. In part to achieve a different look, and in part in self-defense.
