Maybe you could coat an unpigmented solution of dichromate on top of the
unhardened gelatine and expose it to UV light to harden it?

Subject: Gum print sizing voodoo!! HELP!!

Okay, so I have to deliver this print by tomorrow to
this gallery, and my two year old took a sharpie and
made a masterpiece out of it.the wonders of
parenthood.

So I started to make another one, but lord and behold,
I didn't have any more sized paper. I decided not to
panic, and thought that if I work quickly I could size
a couple of sheets to get me through.but I ran out of
glyoxal, I started to get teary eyes, when I remember
I had a bottle of black magic hardener (LPP 92/LPE
520), which I read on this list, was Gluthardhyde. I
added 6ml to my 1000 ml of gelatin, coated my paper,
waited anxiously for it to dry, proceeded to apply my
first coat of magenta and exposed, but the print never
develop. Even with a hard water hose nothing washed
off. I tried this several times, just to make sure,
and all I have are large magenta rectangles. Its like
the sizing is holding the pigment in. I even put an
unexposed (but coated) piece of paper in the water and
the pigment did not released. And just to make sure
that the problem was not in the emulsion I coated a
piece of paper that was hardened in glyoxal and that
cleared!
What am I doing wrong? I really need to finish this
print and my glyoxal is not going to get here on
time.. Maybe I am not using the black magic hardener
correctly?

Thank you,
Carmen
