Ilford Hardener

[Marc Leest]

Hello,

I still have a bottle of Ilford Hardener. What is it chemically ? I might use it for some alt. processes.

thanks, Marc

Should be Potassium alum, or similar. Not much use for anything else.

Not sure about the Ilford product, but if you check the MSDS for the product, it will give you a hint what is in it. Kodak's hardener is primarily glutaraldehyde, which is useful in hardening gelatin sizing if you happen to be doing gum dichromate printing.
