Hi Barbara;

    I've not seen silver cast in brass molds, but I suppose it would
    work. If you try this, make sure the mold has been properly sooted
    so the silver doesn't stick to it. I believe you'll have to heat the
    mold to at least a couple hundred degrees F. for it to work. My
    father used to work as a pewtersmith in an historical village crafts
    program, and he used a lot of old brass spoon molds for casting
    pewter (actually Britania metal, an alloy of tin and antimony, real
    old pewter contained lead and is no longer in use). I wonder if your
    mold wasn't actually designed to be used to cast pewter. With
    pewter, the mold would still get sooted, but the mold temperature
    could be a lot cooler.
