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

[Francesco Fragomeni]

Hi All,

Just a quick question here. Will platinum, palladium, and the ferric
oxalate degrade if they are mixed into coating solutions and then stored?
I'm thinking about an experiment in which a larger than usual amount of a
coating solution will be mixed and will need to be stored but I don't want
to waste time and money on this if the mixed solutions wont last. Basically
paper will be floated on the solutions which is why larger amounts need to
be mixed and then stored in between printing sessions.

Any insight? Will there be any issues with mixed solutions being stored?
