Reid, You're talking about saturating the filter elements in CS then drying and firing them, correct?
Are the filter elements themselve produced locally? From what kind of clay medium are they made? If it's a powdered or crushed dry clay that is re-hydrated before forming or slip casting, would it make sense to use water with silver in it to wet the clay? Then the bisque firing will incorporate the silver right in the substrate, in a fashion that will keep the silver bound but available, I'd bet. There's no way I can think of to avoid blackening in a reducing atmosphere, but then I've got *no* experience there. On the other hand, are you sure that the oxide is not an acceptable form for the silver? Interesting project. Thanks for sharing it with us.
