    There is no clay body that matures at low enough temps to be
    vitreous at PMC firing temperatures, and no, PMC can't be fired
    higher without melting. However, pots can be raku-fired at around
    1650, and some people have added PMC to clay pieces that way. The
    greater shrinkage of silver clay as compared to ceramic clay means
    that they would have to be combined with considerable care. 

    That said, I think where there's a will, there's a way. As long as
    your friend understands how both materials work, experimentation
    should pay off. I would think PMC could be fired onto already-fired
    pottery, as long as the cooling process was geared to the clay.
    Could be fun! 

    I'm pretty sure there was an article on this subject in Ceramics
    Monthly maybe 4 or 5 years ago.
