[Jewelry making - Article 00184] - [Orchid] Holding very large flasks

    I have always struggled holding 4 and 5 inch flasks with the typical
    tongs throughout the casting cycle. This weekend I placed a model in
    a 6 inch flask. The problem was how to hold it when removing it from
    the burn out oven and then hold it while quenching it. 

    My solution worked well for me. I removed a small amount of
    investment from the edge of the flask on both ends after the
    investment set. I placed the large flasks near the front edge of the
    burn out oven. After burn out I used a large pair of vice grip
    pliers to grab the edge of the flask that was uncovered by the
    removed investment and lift it out of the oven and place it on its
    side on the vacuum table. I removed the vice grips from the non sprue
    end and gripped the sprue end of the flask and placed it on the pad.
    Once the metal was poured I lifted the flask by the vice grips and
    set it aside to cool. I held the flask with the vice grips while I
    quenched it. 

    The flask was held very securely by the vice grips throughout the
    casting process.
