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!

  • Bricks, I need some insight

    I have read quite a few posts here and looked at other sites also. My question lies in the bricks, I have the chance to get over 1000 red bricks for free as long as I load and carry. The possible problem is these bricks have 3 holes in them and I am assuming that they will not be sufficent for use as a main component of the oven. I know I can use them to finish the oven but not anywhere heat might transfer. Am I correct?

    you are correct, your best bet is to use them as "window dressing" for the finished look

      1000 bricks sounds like a great stand to me.......

        those bricks are not for the oven but for the outside of the oven (decorative). Don't use them for any part that will be hit by flame.

          They recommend not to use wire cuts, even though, they are fired at a much higher temp than youll ever achieve with a wfo.

            Al,
            Why do you think this is?

              I was always told by the old timers that the air that may be trapped in the holes would expand and explode the brick, sounds like crap to me though.

              I have seen old baked, not fired, bricks used in fireplaces that have stood up to the test of time, there really isnt a reason when you think about it why a wire cut brick shouldnt be used.

              (The old baked bricks are doughy and easily crumbled, fired bricks are hard and vitrified.)

                The composition of the brick is more important. Bricks containing more than 5% iron oxide for instance are more brittle. likewise a high proportion of silica in the clay is undesirable. Looking at brick or breaking it with a hammer is no indication of what it contains. Generally the higher they are fired the stronger they'll be, but a firebrick can often be way weaker in strength than a solid standard clay brick. Insulating firebricks for example can be easily broken with a few taps, yet are probably good for 1300C+ and will not spall from heat.
                A forum member, from Africa, if I remember correctly, used wire cut bricks with holes in them and filled the holes with clay (ant hills I think) this essentially gives you a solid brick and should work ok. I can't recall if he ever reported back re the success or failure of this experiment. A 50/50 sand clay mix should cope with the tendency of the clay to shrink in the holes.
