Ive been doing a fairly good amount of gum over pt/pds the last few months (thanks to Clay for his informal intro to it) I usually dont start technical question threads as 99% of the time theres an existing thread about whatever it is that Im asking. In this case, I couldnt find anything in the forum in regards to this. My question, whats the archival nature of Gum Over pt/pds? Does the Gum Bichromate layer hurt the inherent archival nature of palladium prints? (as Ive read in more than a few counts of the longevity claims of pt/pd prints - even seen first hand a few platinum prints that are 100+ yrs old) Or does is add to its archival nature? or just not effect it at all. Not something Im really worried about ... as I imagine my growing stack of prints will sit in a draw in some desolate house long after Ive left this earth. But curiosity sparked the thought in my head. Along with a question a fellow photographer asked me about the Gum over palladiums Ive been doing as of late. I sat coating two prints with their 3rd gum layers last night and was again curious about this. (posted one of them in the gallery if you are curious thanks in advance.
