Has anyone seen ceramic components displaying brownish/ tarnish after being stored for a period of time? These components have silver finish. I do not know for sure if it's silver oxide or not. Could this be atmosphere condition (eg. humidity, air circulation) related? It appears to be cosmetic only and does not affect the functional requirement. But how would one go about removing such layer on the surface. Rgds, Peter __________________________________________________ Do You Yahoo!?
