Christina,
I've had some recent success in using a Sprint aluminum sulphate hardening bath (360ml hardener/liter) for hardening ossein-sized papers for gum printing. Intuitively I don't think it works as well as formaldehyde, but so far I have avoided staining using up to 4 layers of gum on these papers. The results of course may vary with the specific paper and I suppose the gelatin as well, but so far it is working. I assume the Tetanal hardener may work as well if it is a similar composition. It should be worth trying in my opinion.

Do I have to harden the Gelatin?
Can I also use Tetenal hardener for it or hat to use?
Thanks
Christina

Then you hardened the gelatin?
