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

Hallo Sandy,

Be sure to do a very good final wash when using EDTA for clearing. If the
wash is not complete you will face that palladium will come off the paper
during time (one or two years).

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.
