Okay, you've convinced me that I should at least try hardening the gelatin
sizing for gum printing.

After browsing the archives I've decided to try using glyoxal. I've already
got a pile of paper sized with two coats of Knox gelatin, so what do I do
now? Can I just soak it 10-15 minutes in 2.5% glyoxal? Is it better to add
it to the sizing from the start?
