[Jewelry making - Article 01343] - [Orchid] Reduction vulcanizing rubber

    I have a complex pendant that I designed in Corel, then cut a model
    in acrylic using an Epilog laser to create a vulcanized mold from. To
    get the detail clear enough I had to make the acrylic version over 3"
    across. I would like to now significantly reduce it in size. To
    refine the design by hand I'll go through several molds (using
    Castaldo Gold) which will reduce it slightly each time. However I'm
    sure I saw a poster in a supply shop that advertised a vulcanizing
    rubber that would shrink 50%. I should have written down a reference,
    but I didn't. I know Castaldo doesn't make it. Has anyone heard of
    this or used it?
