>         Has anyone tried enameling on Argentium? 

    Not on Argentium, but on the hardenable silver produced by Johnson
    Matthey. What I found was that enamelling hardened the metal, and it
    also started a process of age hardening. This lead to the pieces
    cracking 3 - 6 months after they were made, i.e. long enough after
    manufacture for them to have been sold. 

    It may be possible that the my designs contributed to the cracking
    and that, for instance counter enamelling wound have prevented the
    problems. But I would be very very wary of using an alloy of this
    type with out extensive and long term testing. 

    If any one is interest I will put some photos of the cracked pieces
    on my website over the weekend.
