RE: Mike Ware's POP Pt./Pd. Pt


Thanks for the link. I was going to ask Mike Ware about this but looks like he has already answered the question.

I also remember something about this is APUG forums. IIRC, the guy who
tried it says it works despite the fact that the sensitizer turns
cloudy. Though I'm pretty sceptical about working w/ a cloudy
sensitizer, and not everyone's criteria match always...

Hi Loris,

Will get the lithium chloride. Your advice has
been outstanding so far, and I am very pleased
with the results.

Just wondering, have you done any work with AFO
and kallitype?  The clearing of prints in
Disodium EDTA made with FAO and Ammonium
Tetrachloropalladate (II) is so quick and easy I
am wondering if the procedure can be adapted to
silver nitrate.

Good news Sandy. I'm glad that you like the alternative sensitizer. Do
yourself a favor and also purchase some (cheap, B&S has it) Lithium
Chloride - to make some Li2PdCl4. (Don't skip this - it's quite a good
hint IMO.)

My pleasure. Best regards,

I finally received some ferric ammonium oxalate today and was able to
do a few tests with Mike Ware's POP Pt./Pd. process. The results were
very encouraging. The Dmax I was able to get with the sensitizer of FAO + Ammonium Tetrachloropalladate (II), on the first try, was
definitely better than I have been able to get with palladium printing
using FO in my working conditions. I am working in a room with about
60% RH, which gives a sepia color print with straight palladium. I am
also exposing by time, not visual inspection.

I would also add that working with the FAO is a real delight compared
to FO. It mixes up quickly and completely in about 5-10 minutes, and
results are very low fog. I am using Mike Ware's recommended
post-exposure processing, which you can find oin his web site
(http://www.mikeware.co.uk/mikeware/Platino-Palladiotype.html), but I
have also found that I can get contrast control with the Disodium EDTA
with dichroamte. Mike does not specifically recommend this approach, as

I recall, but I find that it gives a lot of flexibility to the

In any event, I thank Loris Medici for putting me on the potential
advantages of FAO. Lots of potential here I believe.
