Is sodium dichromate light sensitive?
I've been reading about alternative processes involving dichromates, and I realize that I have large amounts of sodium dicrhomate (in the form of tray cleaner) sitting in my developer shelf. The, maybe, 1/16th of a bottle that I used for making up reversal bleach is still going after processing a 4x5 sheet, a 120 roll and 2 135 rolls of film, so I'm thinking this is going to last FOREVER.
So, my question is, can this sodium dichromate be used in alternative processes as a light sensitive agent (I know it would have to be isolated from the other chemistry in the solution, but that's another issue).
Does anyone know?
