RE: Gelatine - Borax - Formaldehyde

Ryuji, thanks again for the info.

I guess I will harden with glut. Today I talked to a chemist frient who's
going to prepare me a 2.5% soln. of glut diluting a 50% soln. He said that
it is used in farms as an additive to the wash water for the cow's feet when
they return from the field into their resting place. He looked very casual
against glut - he said that he doesn't use a fume hood when diluting 50%
glut!!! Well, anyway I will be very attentive using the relatively mild
soln. provided by him...

Regards,
Loris.

As you see here, glut will simplify life a lot. You could simply stir in 0.5
to 1g of glut per 100g dry gelatin and coat. By the time the paper is
completely dry, the hardening is done. There's little excess hardener to
worry about.
