[Jewelry making - Article 00782] - [Orchid] Bellicold Mold Gives Alexander the Great a Double Chin

    I found a place in the Czech republic that makes amazing copies of
    ancient coins in gold, silver, and very affordable tin (they're very
    upfront about their replica business, they do not appear to be trying
    to pull the wool over anybody's eyes, and their products are
    excellent).  I bought some of the coins in tin and tried to make
    molds of them for PMC using very new, fresh Bellicold from Rio.  It
    worked well except that there seemed to be no way to strike the right
    balance between pushing the coin into the molding material just
    enough to make a good impression, vs. pushing it in too far and
    giving the face concerned a double chin.  (The Bellicold added 30
    years to my Alexander the Great, giving him a honking double chin;
    Colin Farrell he is not).  I have had great success molding things
    beside profiles of faces in Bellicold, however.  It just doesn't seem
    to do well with any shallow design. 

    I experimented with molding only one side of the coin using an RTV
    kit from TAP Plastics, and the mold turned out just great.  I have
    yet to actually use it to mold PMC so there may be unpleasant
    surprises ahead.  My question is, has anyone made molds for PMC using
    more high-end molding material such as Castaldo, and is there any
    reason to use it instead of the cheaper and more easily available
    stuff from TAP when all you're doing is making a mold for PMC? 

    If the Czech company makes an exact copy (no added design touches)
    of a 2,000 year-old coin (very much out of copyright, assuming it was
    ever in) and then I make a mold of the Czech company's copy and sell
    the jewelry, am I violating any copyright laws?
