RE: Ferric Oxalate or Ferric Ammonium Oxalate


BTW, what procedure do you follow for making Ziatypes?

I've used a lot of FAO for making ziatypes and Ferric Oxalate for making DOP
palladium and never had a problem with either.

I assume chemically FAO is considered to be more stable than FO so from that
respect one might assume that it is a better choice than FO.

After looking at some very beautiful prints made by Loris Medici
using FAO I am evaluating the prospect of shifting from FO to FAO. A
recent major lack of inconsistency in results from batches of of FO
motivates in part this interest. Mike Ware recommends FAO, noting
that FO is a very ill-defined substance.

Just wondering what some of the other Pt./Pd. printers on this list
think, pros and cons FO versus FAO?
