Green Sludge in Pot Ox Developer
I had some green sludge in my potassium oxalate developer for my pd prints yesterday. Any ideas on what it is? My thought is that it is crystalized pot ox because I had the developer in an open tray for about 4 hours, definitely long enough for H2O to evaporate and the pot ox to leave solution and precipitate.
Let's see what I've got in the magic trash can for Mateo!
PO developer returns to a crystal state, not a sludge. There may be some excess palladium metal in the developer which can be removed by filtering through a coffee filter. If you add some more water and heat it up a bit, the PO will go back into solution. If anything remains it might be Pd metal. Then again, I don't know what the quality of your water is.
This is normal. Just filter it out and move on. No harm done.
