RE: Ware/Malde-Ziatype-DOP palladium,was RE: "New" Paper for Pt/Pd (and other iron processes, too)
Clay, I agree: the more fundamental difference is the use of ammonium salts vs lithium. However, I didn't bring that up because I was under the impression that Sandy used lithium salts across the board. Therefore, when I asked about a comparison with the sodium tungstate added, I assumed the lithium vs. ammonium aspect was a non-issue. Loris, thanks for the examples, that was just what I was looking for. It's good to see that I can achieve a nice middle ground between too yellow and too red with the ziatype.
