RE: Ferric Oxalate or Ferric Ammonium Oxalate
Don, BTW, what procedure do you follow for making Ziatypes?

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.

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? Sandy King
