FW: Staining for argyria?

From:Roy Ellis

A rhodanine stain for silver (similar to that used for copper) exists, but
the simplest method of demonstrating silver is to place sections in a
solution of 1% potassium ferricyanide in 20% sodium thiosulphate. This
causes decolorization of metallic silver by oxidation.
