Does anyone know the aging characteristics of ferric oxalate #1 solution
and the effect of aged #1 solution on the final print?
1) Is there any difference between freshly mixed ferric oxalate and for
example three week old ferric oxalate ?
2) Is it recommended to mix fresh ferric oxalate each printing session?
3) Does refridgeration of the mixed #1 solution after printing slow down
the aging process.
4) How about the aging of #2 solution: ferric oxalate and potassium
chlorate and the need to mix the solution fresh each printing session?
Thanks in advance
