[Jewelry making - Article 00078] - [Orchid] Depletion silvering

    Several Orchidians have said they repeatedly heat and pickle a
    sterling object in order to bring up a layer of fine silver. 

    I was wondering how hot the sterling needs to get and how many
    cycles are typically needed to bring up the silver. 

    With respect to tarnish, does the finished piece act like fine
    silver, or does the copper in the base migrate to the surface and
    oxidize? 

Salud,
Janet
