Terrific article. I printed it out and would like to try Pyrocat instead of the Rollo Pyro which I now use. However Sandy says you should mix the stock solutions under a hood or outside.
I live in an apartment house - no hood and hard to work outside. Photographer's Formulary
only supplies the powder although they do provide the stock solutions for several other Pyro developers. Why don't they supply Pyrocat in liquid form. Is there some reason for only supplying the powder?
