Grobet casting metals are non-
precious alloys that resemble gold
and silver that are used as
inexpensive casting metals.
They may be oxidized, antiqued, or
plated. The metals are tarnish
resistant and will not discolor when
heated. They come out of
investment bright and shiny,
reducing the need for stripping or
pickling. Electroplate or solder with
gold or silver solder.
