    Joseph: I built a blast furnace about 15 years ago in my back Yard..
    It measured 24" high x 12" inside diam. and it has a 4" thick wall
    and a 4" bottom. I contacted a Refractory cement co. in Los angeles
    and went and talked to the people and told them what I wanted and
    they sole me the refractory cement to do the job   I used a
    Volkswagon wheel for the top and filled it full of the cement and
    built a device to lift the top up and pivot it out of the way si 

    I could load the furnace with crucible and bronze. 

    I set it up to use bottle gas which I have used and it will melt
    23lb. bronze in 45 minutes from cold start. 

    I went to El Camino Coledge and asked the prof if I could look at
    their furnice and take measurements and he gave me permioion and it
    came out great.  I am a certified field welder for heavy gage metal
    so it was easy to do the project. 

    If you need more help e-mail me and I will be glad to give you
    further pointers on making the furnace. Yours: Billy S. Bates
