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!

  • Fire brick mortar

    Hi, I am looking for some help with the thicness to apply the mortar between firebricks, the guidelines indicate 1/8" maximum, but It will need to be thicker towards the outside of the dome where the bricks splay out.
    Is it okay to use a thicker joint here.
    I would welcome any help

    Yes you can use a wider joint at the outside, you will need to unless you go crazy with cutting and fitting. What mortar are you using?

        From the Victas site:
        Victas heat proof mortar is suitable for all kinds of INTERIOR use, but must not to be used outdoors.

        This looks like a premixed air-set product. Some people have used this successfully, but it will remain water soluble. Better to get a dry refractory product if possible...

          I will look for a dry refractory product as suggested, not easy to find in the Uk so far, Vitcas assured me it would be okay as long as it was weatherproofed.
          This is a great site, really helpfull.

            I'm with Drake on this.

            It's very difficult keeping an outdoor oven dry -- no matter how hard you try to weatherproof it. The issue is that the binder that holds the mortar together comes apart when it gets wet. Not good.

              Doesn't burning the wood and baking produce water vapor. Is it enough to damage the air dry mortar or are things too hot in there?

                It's the rain, fog and mist. The mortar can't ever be exposed to water.
