>Pete, that is indeed a fascinating report<
Thanks for
the kind words Judy
>Meanwhile, since, as you know, each question answered raises two
additional
ones -- your next task is some form of accelerated aging test of
pigment/stain and paper in combination to see just how deleterious
different levels of stain in the various conditions are.<
Yes this is the next logical step, the problem is we know so little of what
actually goes on inside the Dichromate colloid emulsion.
>We have taken as gospel for years that, aesthetics aside, residual
chemical is unarchival. In all forms? In all amounts? Especially given
possible color and scale benefits,<
Yes we do find that a lot of accepted truths do not stand up to close
practical scrutiny, as you have found out in the Paul Anderson tests for
pigment stain, and many others
>I recently read about an accelerated aging test you can do at home alone.
I'll see if I can find the info<
Most interesting,
pete.
