Ferric Oxalate or Ferric Ammonium Oxalate
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? Sandy King
