New Forno Bravo Forum Feature

Forno Bravo Forum Community,

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.

To kick off our AMA feature, we have invited author, chef and master bread maker and host of Pizza Quest, Peter Reinhart, to be our first host! Peter will be in the Forum on Monday, February 15th, from 7:00 - 8:00 pm EST. If you are unable to be online during the live session, you can post your questions in the sticky post. Peter will answer those questions during the live session on February 15th. You can view Peter's answers to your questions as well as what happened during the live session in the session thread.

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!

    Hi All

    Im just getting started building a wood oven.
    I am doing it on a tight budget and using materials i can get through contacts at work cheap.

    My base is going to be made out of railway sleepers, 9 x 5, with Reinforced bar going through them to keep them all secure.
    On top of them will be a line of sleepers giving a 5inch slab. On top of those will be Paving slabs, 2 inch thick. Then Thermalite bricks as an insulating layer between the oven floor and the slabs.
    I am purchasing a premade cast oven that will need insulating and rendering on the outside.

    However, i would like enclose the oven in and insulate with loose Vermiculate/Cermaic Fibre blanket.

    My question is, i dont want to brick lay on top of the slabs/sleepers base due to weight. However i am handy with timber and have the means and skills to construct a nice looking timber "house" surround for the oven.
    In this i can pour in the insulation and construct a roof.
    Do you think that the heat passing from the oven will be low enough through all the insulation so that the timber will not be affected?
    If it will only get warm then that is ok. I just dont want it burning down!

    These things get very hot - over 1000 F. Often hot coals will pop out the opening.

    I would serious re-think using timber anywhere in the structure.

      Re: Design Help

      I recently inspected a brick oven that was built over a timber stand. It had a thin sheet of coated steel over the stand and then two layers of solid 3" bricks sandwiching a 1" layer of clay, for the floor, with the oven built over the top. The heat had penetrated through the bricks and burnt the timber supports in the centre. As the dome was built over the floor I could not work out a way to remove the floor, repair the burnt stand and add an insulation layer.I suggested he demolish and start again. A real pity, with all that brick cutting and dome work gone to waste.
      Kindled with zeal and fired with passion.
