[Alt-photo] Re: Longevity of Pt/Pl chemistry after being mixed?

[Francesco Fragomeni]

Yes to clarify, I don't mean the longevity of the individual parts
independent of one another. I mean the longevity of an actual coating
solution once mixed i.e the Platinum, palladium, and ferric oxalate 1 and 2
mixed together and ready for the paper.
