Just catching this thread, which has been pretty well covered.
Except, Lenox too is variable. After using it as one of my two main papers
for a couple of years now, my most recent batch might as well be another
paper. It's whiter, (not necessarily bad) smoother, (ditto), but requires a
lot more solution to coat (bad) and pure palladium prints come out bright
pink (very, very, bad) instead of the beautiful mahogany color I'd been
getting. It's still useable if given an oxalic acid presoak and coated with
a 25% platinum mixture, but I'd really like the old stuff back again.
On clearing, what strength are you using the citric? I've found that Lenox
and some other papers I use clear *almost* (but never fully) completely in a
weak (1 tblsp. per liter, which is very roughly 2%) citric acid bath after
ten minutes or so, and then finish clearing, *blam!* when moved to a second
bath of EDTA/sulfite. The citric turns color very quickly, as in one 8x10
per quart. Since you are a chemist and I'm not, I'm curious whether this
makes technical sense as a clearing regimen, and also how to judge the
capacity of the baths--throw them out when they show the slightest signs of
discoloration, or keep them till they look like a substance much-discussed
of late on the list, or perhaps somewhere in between?
