Hi Maureen,

    The melted silver is a rolling sphere, though not orange, it looks
    more like mercury. I sprinkled in the borax and swirled the crucible
    around 'till it dissolved. I don't have a graphite rod. I did indeed
    keep the torch on the silver as I poured it, and the distance as
    short as possible. I also wondered about whether it has anything to
    do with the Argentium. To complicate matters, there are two types
    that Rio sells. I have to dig up my old receipt to remember which
    one I ended up with. I am going to try putting the air vent(s) over
    the thin part to see if that helps. I have wondered about making two
    sprues, but dont know if splitting the flow of silver when pouring
    will cause porosity or faster cooling or other problems. I guess I
    should just try it.
