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

[Loris Medici]

I haven't. (Because I haven't mixed palladium or platinum solutions from
precursor salts, yet! Hehehe...)

But I remember seeing this:

"... Even when dry, palladium(II) chloride is able to rapidly stain
stainless steel. Thus, palladium(II) chloride solutions are sometimes used
to test for the corrosion-resistance of stainless steel.[7] ..."

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?
