Cold Bath Developer - PT/PD
I have run across a formula for PT/PD Cold Bath Developer which is as
follows:
175 gm Pot Oxalate, 75 gm Pot mono Phosphate and 1 qt. H2O
The implication here is that Pot Oxalate can also be a dry powder (it was
probably first a dry powder). However, I only know Pot Oxalate as a
solution prepared from Pot Carbonate and Oxalic Acid.
The question is, how would one go about modifying the above formula to
prepare a qt. of Cold Bath Developer if you were to start with a quart of
Pot Oxalate in solution form, or could you???
Seems like one would just add the Phosphate - but as we all know it's
usually not that simple.
Many thanks,
Nick
