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!

  • Floor blocks spreading?

    HI
    I have had my 900mm homebuild firebrick oven up and cooking well for 6 months now. Cooks great.
    However the firebrick floor was set with no gaps between them and now the ash has gotten between the bricks and seems to be spreading the bricks apart. The bricks were laid on hebal with fireclay as listed in the plans.
    The gaps seem to be getting bigger and a CRACK IS NOW FORMING in the dome in line with the biggest floor gap.

    Can this be stopped?
    Can i clean out all the ash from the gaps and fill it with hi temp morter etc to stop this.
    I am concerned if the dome cracks then the insulating blanket fibres could enter the dome during cooking. Idid not cover the dome in al foil before insulating as I did not want to trap water in.
    Any thoughts?

    The ash is filling the expansion in the joints between the firebricks, not causing the problem.

      HI and thanks Brickie
      Do you think this will settle down and the crack will stay the way it is?
      It's been the same size for a while now and does not effect the cooking ablity in any way.
      I love my new oven and would hate to have to rebuild it.
      I get people ask when are they getting invites again !!!

        Could the hebal, be causing the problem?

          Don't worry about the gaps in the floor bricks, they allow for expansion and will fill with ash. Just leave the ash in there. Regarding the dome crack, it is just your dome finding its "comfort zone" from the expansion and contraction cycles. They usually don't get any worse, but if it's bigger than being able to fit a playing card in it you could try to fill it. It is usually only partially successful though. You may be right the expansion and contraction of the dome against the blanket could abrade it and some fibres could find their way into the oven. The fibres are only dangerous to inhale not to ingest. To plug the crack dampen around the crack, wait a few minutes then try squishing in a mixture of equal parts fine sand, fireclay and lime.
