    Rebecca: Don't do it!! Unless the plaster is formulated for high
    heat and  has been baked for a considerable length of time  in a
    oven it will still contain water. When the hot metal hits the
    plaster the water will be released as steam and you will have a
    miniature volcano. Hot metal (red hot) will fly through the air and
    land in the most unfortunate of places. Like on you.... If you want
    to pursue this technique try cuttle bone casting. Two pieces of
    cuttlebone are wired together after the pattern is carved into the
    surface. Molten metal is then poured into the pattern through
    channels carved into the cuttle bone. Not to dissuade you from your
    creative process, but when dealing with molten metal KNOW what you
    are doing before you try experimenting. The results of lack of
    knowledge combined with 1800 degrees plus of hot metal can be very
    dangerous. I suggest you take a few classes or do some really
    serious reading before you continue your project. Frank Goss
