Hi Gang,

>     You can find firebricks at most home supply place. They are soft
>     and can be cut Into smaller pieces. 

    Be careful getting firebricks from home centers. Usually the
    firebrick they sell is the hard variety used for lining furnaces etc. 


    The fire brick you want is made of a magnesia material. It's much
    lighter in weight than the firebricks typically sold at home
    centers. The 'soft' firebricks are usually called silversmiths
    firebrick. They're soft enough to stick a straight pin into.. Try
    sticking a pin into the brick before you buy it. If you can't, it's
    probably not the one you want. 

Dave
