    Dede, Multiply the weight of the wax model by 10.4 (relative weight
    in sterling).  That gives the weight of the piece in silver.  Many
    folks also multiply the result by 1.25 to provide extra silver for
    the button (the extra silver that appears above the sprue after
    casting) to allow the casting to draw extra metal as it cools.  This
    often involks disagreements amongst caster....some say it is not
    necessary, others say it is essential. To be safe when starting out,
    add in the extra!

    elegance IS fine jewelry! dcdietz AT comcast.net
