I have two questions for anyone on the list who might be able to
share some knowledge.
The issue is this. For some time I have been making platinum and
palladium toned kallitypes. Some of the literature on toning
indicates that during metal toning the more noble metal plates the
less noble one. Other literature indicates that the more noble metal
actually replaces, either completely or in part, the less noble one.
What I would like to know is this.
1. How would one be able to find out whether when toning a silver
image with gold, palladium or platinum the toning action is resulting
in plating or in replacement of silver metal?
2. Assuming that toning with gold, palladium and platinum results in
replacement of silver metal, how would one test for the presence of
silver to verify whether the replacement is partial or complete.
