Re: A few gum things

Dear List,
My apologies for the present mail adressed to Diana Bloomfield whom I'm unable to reach by email.
Hi Diana,

So, here we are in april and I just wanted to give you a few pointers in
order to be as economic as possible for your upcoming show. When you mail me
your work I prefer to get it unmatted (as I have the necessary equipment)
and I recommend to send it as "exhibition photographs without commercial
value to be remailed to sender after exhibit". If you state a commercial
value I will have to pay a proportional import tax.
I can hang about 20 images in 30x40cm and 40x50cm frames.

Thank you for showing your work at Atelier pH7 in the beautiful city of
Sorry again.

I use gelatin / dichromate to size papers. Works quite well for me in a tri colour gum. I am not sure what is the procedure that James has, so I can not comment on it. You have to remember that dichromates are not the crosslinking agent. They have to be converted Cr (VI) from the dichromate to  Cr (III), by either dark reaction, which is slow, or UV light. I coat with gelatin / dichromate , let dry and expose to sunlight for 15-30 minutes to harden the gelatin. I can email details if you want to try.
