Judy:
Correct me if I misunderstood you. You have some selenium toner formulas,
and at least one of them is of the bleach and redevelop kind. I have tried
to do just that several times in the past using Kodak's toner with no
results whatsoever. And now you have given the answer: the toner has hypo in
it. Could you please be so kind to post your formulas? If you have any
safety concern, you could send them directly to me (I studied chemistry for
years before becoming a photographer), but I think there is a lot of
interest in the list.
Some more questions, do you have pure selenium or some kind of
selenide/nite? If you have pure selenium do you mix it with some kind of
sulfite or sulfate? Where did you find it? My last catalog of Photographers'
Formulary does not include it (it is at least 3 years old).
I will be eternally in debt to you.
