I'm interested in learning more about using a direct polysulfide toner like Kodak T-8 or Formulary Polysulfide Toner for archival toning at a high dilution like 1:100. I've been reading through Darkroom Cookbook, Film Developing Cookbook, and other papers, and other forum posts, and there's a consensus that even a quick dip in a 1:100 dilution of Kodak T-8 will provide archival qualities with minor (or any!) effect on the hue of the print. That's enticing to me as I really enjoy the original qualities of Ilford MGFBWT paper. I understand proper two bath fixing and washing is of utmost importance, but a little insurance via polysulfide toning would be nice!
The capacity of 1 liter of Kodak T-8 or Formulary Polysulfide Toner is listed as 35 8x10 prints per liter, but The Darkroom Cookbook and other places recommend also using it 1:100 for archival purposes (3-5m @ 70ºF). Dividing 1L of working solution by 35 prints would assume about 28ml of stock is required per print, meaning 2800ml of working solution for one single print at 1:100 dilution. That seems ridiculous. How would I go about figuring out the capacity of 1 liter of the archival 1:100 working solution?
Anyone have any experience of using these toners 1:100?
