Chris, there are some things that are true and this is no myth. Coating
brushes with metal in the construction is asking for "seasoning" by your
solutions as well contamination of your coating. Plastic and glass are best
to use around pt/pd and for my money; all alt processes. In an educational
environment, I'd go with plastic for the safety of less dexterous
individuals. (breakage).

Subject: [alt-photo] mixing platinum in stainless steel container

Dear All,
Well, start to a new school year and I am never fully ready.
I was going through old magazine articles preparing for class and came
across a funny article from Darkroom Photography (1987) where photographers
shared their darkroom nightmares. In there, George Tice shared a story about
mixing platinum in a stainless steel tank, and that the chemistry reacted
with the iron in the stainless stell and not only badly pitted the stainless
steel tank but also he had to have a chemist remove the iron chemically from
the platinum solution to salvage it.

George Tice is an inveterate platinum printer. I have not heard this. I was
wondering if anyone else has experienced this?
Chris
