    Karen, What was your master made of? If you are using a natural
    rubber such as Castaldo gold bronze, brass or copper models will
    leave a brown oxide film that is baked into the rubber and coats the
    mold surface.  Always Siver plate a copper based master. 

    Also, too high a wax temp. or too warm a mold would cause these
    problems. There might also be an incompatability between silicone and
    natural rubber. 

Good luck,  Andy Cooperman
