[Jewelry making - Article 00545] - [Orchid] Wax castings

    I have been trying unsuccessfully this summer to take wax castings
    from clay moulds and wonder if any Orchidians can help out.  I've
    made a clay impression of textured rocks. The idea was to pour molten
    wax into the mould and then I'd get a positive impression of the rock
    texture.  I have been using a very fine earthenware red clay from a
    potter friend. It successfully picks up minute detail.  I have tried
    every type of wax I had on hand (red, blue and a green "Pour-a-Tex"
    and most recently a turquoise injection wax). I've tried pouring the
    wax in when the clay is wet, dry, very dry, heated in the oven to
    about 300 - 350 degrees F. The problem is that bubbles begin to form
    in the wax once it hits the mould regardless of the temperature or
    dryness/wetness of the clay.  My idea had been to soak off the clay
    once the wax had set, with little damage to the wax. 

    Any suggestions or hints would be greatly appreciated.
