  • Re: Steel Dome Oven

    Buckeyebreadman,
    Using a layer of soapstone where I used a thin layer of firebricks should work fine. The thinner layer of firebricks was to provide a stronger more wear resistant surface for the steel dome to sit upon rather than simply sitting the dome upon soft vermicrete. I was concerned as the steel dome expands and contracts with each firing that it would slowly wear into it. This could potentially cause all sorts of problems with intimate contact (think heat transfer) from the steel dome to the refractory heat reservoir overlaying it.

    Soapstone is also known as talc and when ground to a fine powder is talcum powder. In this case I would expect the soapstone (although softer than a firebrick) would act as a self lubricating surface. It should work very well.

    Bests,
    Wiley

        If there's a slower build I don't want to know about it.
        I actually opted for 2" of insulation board on top of 4" of vermicrete.
        I'll now add a layer just like Wiley did. The thinner Firebrick and the usual thicker ones (2 1/4"?) Going on Three years and that's where I sit. Should get the dome on this spring. I'll update then.
        The soapstone was just too expensive.
