Hi All:

    This may or may not apply to you're project but I thought it
    interesting! Years ago I built my own forge and was helped by a
    sculptor who worked at N.A.U. He showed me how to make a five part
    refactory mix that would line the firebox on the forge. It consisted
    of equal parts of Portland Cement,River Sand,Vermiculite,Sawdust and
    Fireclay. It was all mixed in a wheelbarrow with a little water until
    when pushed around it would clump up good and stay in position. Then
    we took a 2x4 and rammed it into the firebox frame (angle iron and
    sheet steel)and trowelled it off to shape. After the initial firing
    of the forge(coal fired) the refactory was cured and did not crack or
    breakdown in any way. The forge used a squirrelcage blower for air
    and was controlled by a footpedal rheostat with a butterfly valve
    for controlling airflow. It worked super and would heat up a round
    steel blank (2"x6") in about three minutes to white hot. Anyway the
    refactory held up great. Hope this is of use to anyone who needs
    material like that. It can be formed into sections and asssembled to
    whatever configuration you would want. 

Best Wishes
Harry
