RE: dichromate stain

Clay says:

"Maybe the chemists in the crowd can put forward a hypothesis as to why iron
rich water would be more likely to induce dichromate stain."

My well water is loaded with iron. It is yellowish coming from the tap, and
turns orange when it sits for a couple of days. And I get no dichromate
stain.

And, to mention another factor that might increase the likelihood of stain,
but doesn't: I develop my prints in horribly dirty dichromate-loaded water.
You can't even see through this stuff. Used dichromate waste is such a
tremendous hassle to deal with, that I put it off changing water for as long
as possible.
