Sandy,
1. When I tried out the process, the point seemed to be that they were
visually identical to platinum and platinum-like kallitype prints.
2. Satista has a cost advantage over platinum, which was the reason for
its introduction. I think the archival properties are likely to be
dependent on the amount of iron left in the print and the state of
division of the silver in the image. Platinum toning has been claimed to
increase the stability of kallitypes.
