Having had some success with Pyrocat-HD and bemoaning the short shelf-life of the stock solution kits from the Formulary, I recently took it upon myself to mix up some of Patrick Gainer's Cat-P-TEA using the recipe in the Photo Techniques article of a couple years back. To do so, I ordered 100g for Pyrocatechin from the Photographer's Formulary. Despite great care in the mixing of the stock solution (and I have prior and successful experience using TEA-based developers) it hasn't been a success. Even extending development times to 13.5 minutes for 400TX I'm left with flat, grainy negatives that show no sign of staining. They look nothing like my negatives developed in Pyrocat-HD and Cat-P-TEA's own formula is clearly inspired by the former (think Pyrocat-HD with TEA substituting for the Carbonate and the absence of the Potassium Bromide). So what's going on? I'm using Formulary TF-4 to fix (which is alkaline and should not inhibit the stain) and no Hypo-Clear or dilute Sodium Sulfite after- bath. I did notice that the Pyrocatechin that the Formulary sent me looked odd. There was a mixture of small off-white granules plus some significantly larger leaves that were flat and triangular or rhobmic in shape. Most of the larger leaves were medium to dark gray in color and gave off an acrid odor. Not having experience with Pyrocatechin before I don't know whether that is normal or not. Can anybody tell me what is amiss? Is it something in my process or simply bad Pyrocatechin?
