Response to PMK Pyro

Interesting idea. I don't think it would work. The after-bath that induces the stain is simply an alkaline solution (sometimes the spent developer is used, but a teaspoon of Kodalk in a quart of water does the same thing). I believe it is the tanning action of pyro on the film emulsion, in combination with an alkaline environment, that is the key to the stain. No tanning action, no stain.
