Mike -- I wish I knew! I was going to mix up some Agfa 8 film developer (water, sodium sulphite, glycin, potassium carbonate, more water), then discovered I was out of potassium carbonate. So I went looking for other glycin developers and found exactly one reference to Edwal 10 (as opposed to Edwal 12, which is well documented). I find it interesting to see the differences between the two -- Agfa 8 uses only glycin as the developing agent, while Edwal 10 uses 2. Uses borax, too. I guess I'll just have to mix some up. Hopefully if someone else has used it, he or she will chime in.
