I understand that Classic Pan sheet film needs a hardening fixer. I can't find a formula for a D.I.Y. hardening fixer. Can anybody help?
best wishes,
Pete.

Digitaltruth has a few formulas:

Add sulphuric acid to make it hardening
The Film Developing Cookbook (Anchell/Troop) contains formulas for a glutaraldehyde hardener and two acid hardeners (Kodak Fixers F-5 and F-6 made without sodium thiosulfate). Do you want any of these formulas? Actually, if you want I could scan the formulas and associated discussion and send them by e-mail.

That's not actually the case. I thought so as well. Please see this thread:

While the subject starts out SLIGHTLY off-topic for you... all the info is in there.
