RE: One coat gum - first one for me - how is it for you?

Hi David,

That's probably because you're keeping the lamp far enough from the frame.
Exposure time of 15mins with "saturated" "potted" dichromate is pretty long
when compared to mine -> BL tubes, 6mins w/ 5%(!) ammo. Dichromate (notice
the soln. strenght difference). Aren't you afraid of dark reaction? I mean
when considering the facts a) Fethiye is hot and humid, b) you're using
relatively long exposure times, I would be concerned about it...

Best regards,
Loris.

Strange, I don't have a problem at all with heat on the print. The varnish
on my table is melting but for some reason the glass stays cool.

Keep on dusting the piano,
