    Re: My Brick Selection ok?

    [QUOTE=john_aero;150961]just spotted this on the pdf file for forno oven. this mean the fire bricks i have are prob not suitable?

    High duty fire brick.
    These brick have very high alumina content (60% or more),
    get very hot (1500?C and up) and are designed for continual
    high-heat applications, such as furnaces.

    How can they get that hot if you stop chucking fuel into the oven?

    What it should say is, These brick have very high alumina content (60% or more),
    and are designed to take temps of (1500?C and up)

            The floor takes the most punishment, so use them there. Bricks that can withstand 1500C are not necessarily suitable for an oven that only reaches 500 C. The thermal shock characteristics are more important and they do not necessarily confer with the temperature the bricks are fired to. An example of this is the low fired sth. American pots that have good thermal shock characteristics but are only fired to around 700C. The clay body is left fairly open and able to withstand sudden temp increases so you can place these pots directly on your stove.

              they are tapered so wont sit on floor.

              could try and sit the on face and stagger them that way would interlock.

              i was wondering if they would do for the 1st 2-3 chains

                I used super duty fire bricks on all of my build they were new surplus from an old steel mill (65% alumina) they don't get any hotter than you let them. They were all tapered so I used them where that tapers allowed for best fit. The only drawback I had is the are very hard on diamond wet saw blades, they wear them very quickly. I went through at least a dozen, but they were the cheapo blades also. You can look at my build to see where I used them. Also, Oasiscdm (aussie) is doing a build with bricks tapered like yours

                    The 60+ alumina kiln brick that I have do not break easily with a brick set. In fact, I can barely mark them with a brick set and hammer
