Ask Me Anything New Forum Feature

You will notice a new forum at the top of the main page called, "Ask Me Anything". This forum will be used for live one hour "Ask Me Anything" (AMA) sessions hosted by people who are knowledgeable in different areas pertaining to wood fired ovens. How it works:
- Each AMA will have a "sticky" thread where the community can post questions they would like answered during the live session. This will allow everyone to participate even if you can't be online for the live session. These questions will not be answered by the host until the live AMA; if you need an answer quickly, you should post it in the appropriate Forum area for the community to respond.
- Another thread will be posted for the live AMA. Registered users who are logged in during the live session can interact with the host by asking questions and receiving responses.
- The live thread will remain in the AMA forum to view after the session.

We hope you enjoy this new feature! Please let us know if there is a topic that you'd like to have as an AMA and we'll look for a host!

  • Granite for oven surface?

    Hi, I'm new and investigating options for building an oven. Is it possible to use 30mm thick granite for the oven surface. I know granite can be heated up to significantly high temperatures and so was wondering if this would be a good long term solution rather than using fire bricks.

    thanks

    First off Rod - Welcome to the group! You are starting down the love hate road of construction and materials and....

    In reading this, I take that you are wanting to use granite for the floor of the oven.

    The simple answer is (drum roll please) NO

    To explain, though granite is beautiful and take some temp, it cannot handle the temperatures you will be subjecting it to due to the pesky Thermodynamics and expansion coefficient for it. If you are set upon using stone for the floor, there are those who have used soapstone with great success. Plus. soapstone is easier to work with and cheaper to purchase (a good thing in my book.) Downside - not as pretty.

    Hope this helps!

      I understand the thermo bit, but if it is in smaller tight nit pattern, will it work or do the stones crumble and so on? Sorry for a possibly dumb question but I am a novice

        It will not crumble it will spall explosively.

          Tscarborough, thank you. I was wondering why it was rarely mentioned apart from decorative work. I wondered if it were a cost thing. I will obviously be steering clear in that case!

            Welcome Kiwi,

            Hope that is not a derogatory name, although granite will not work, some builds have used soapstone for their floors, IE, GianniFocaccia or heater tiles - Bookemdano. With the high cost of firebrick in AU and NZ can't blame you for looking for an alternative floor option.

                use home brew for your refractory mortar.

                Build a house around your oven and insulate first with Ceramic fiber board for floor and blanket for dome, suplement with verimicrete for floor and pour perlite or vermicrete into house over dome.

                Lowers operating cost of oven by lowering your wood usage and improving cooking capibilities due to heat retention.

                Search craigslist for building materials, make a well fitting well insulated door for heat retention.
