The potassium oxalate I had left was a too small amount of solution that had
held out for over two years but was ready for a change since it had not been
replenished for quite some time and was too little to cover the print. I
should have said it had reached its "throw out" point.

I use potassium oxalate as my regular developer for a number of reasons. It
seems to be more active, requiring less exposure for a print. Prints
developed in Bromo Seltzer (sodium citrate) require about 30 to 50% more
exposure. Prints developed in MSG require a bit more again. Since I make
many of my prints on fixed out baryta paper which requires up to three times
the exposure as a print on cotton papers, this can be a big deal. Potassim
oxalate also gives me an image colour that I like, although sodium citrate
gives a very pleasant warm tone to palladium prints which I like very much.
MSG tends to give a cooler tone and in some prints a bit of grain.

Indeed, no matter what it is developed in, Pot Ox, MSG or...Sodium Ascorbate
my next project.
