Re: Aging Dichromate (among other chemicals)

 I was using thiourea dioxide in "Manotone" as a
> plating-out toner.

Judy,
     Are you being sexist here? :)

     The weirdest happening I had with chemicals was with liquid emulsion.
I had a couple ounces (unrefrigerated) left over in a bottle that was well
over a year old. I decided to use it and see if it still was OK, and it
was. Hot darn, I thought; I did some prints, and some more, and then all of
a sudden the whole batch was fogged grey. Of course, I had coated quite a
bit of paper that I then had to toss (and, no, Mark Nelson, I did not leave
the darkroom light on while drying the coated paper hehehehehe).
