RE: My first GumPrint-some Questions....

I've used the Ilford film hardener as well, it works but as Joe says,
not as well as formaldehyde.

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?
