I have taken the casting class at the Maryland Institute and it
was very good. The instructor, Shana Kroiz, also teaches at the
92nd Street Y in NYC. One of our projects was to carve a wax
piece which was to be a link in a bracelet or neckpiece. We then
learned how to make our own mold of the wax piece and made
multiples of it--all of which we cast. The mold does not need to
be made from a silver piece.
