    This sounds dangerous. 

    Rick what has worked for me is a Raytex dopping unit. I don't know if
    they still make these. It's 7" x 4" x 4" metal box that uses a 100
    watt bulb as the heating element. I just used it to heat a large
    irregular opal which I glued to a piece of MDF. My reason was to
    protect the face and to use the MDF as a holder for sawing. 

    I heated both the stone and MDF on the dopping unit, and then used a
    heat gun and a glue stick to glue the stone to the MDF. I turned off
    the dopping unit and let the stone and MDF cool down on the dopping
    unit. 

    I've heating opals to the point that you would burn your fingers if
    you tried to pick them up. It's thermal shock that destroys stone not
    the temperature.
