Getting a warm tone out of ARISTA.EDU paper

Yes, the original German Agfa formula for Agfa 120 calls for both Potassium Carbonate and Potassium Sulfite. The German Agfa 123 formula is identical to Agfa 120 with the addition of Potassium Bromide and claims browner tones as a result. I would not expect the use of Sodium salts to cause a color difference.

I use "German Agfa" to distinguish from "USA Agfa" which used some of the same formula numbers with different chemistry.

Andre,

I hope the Agfa 120 works out for you. I had been using Agfa Neutol WA before switching to the PG/PQ developer, and while similar, I much prefer the PG/PQ, and as I noted above, I expect the image to warm with dilution, which will aslo bring the cost/liter down into the 10-25 cents/liter range. If I could get my scanner to work, I could post some images made from negatives and paper developed in PG/PQ. Good luck, and I look forward to seeing your images posted.

Jay, I have been developing Kodak TMY in Pat Gainer's PC-TEA with excellent results. I have done some Azo contact printing with PC-TEA as well. I can get a wide range of tones with it by adding Benzotriazole and I can manipulate the contrast with a combination of Benzotriazole and dilution.

Lord knows what the shelf life is - but it is LOOOOONG!
