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!

  • aerated autoclaved concrete

    Has anyone ever built an oven on aerated autoclaved concrete (ytong,hebel blocks). The R-value is 1.25 an inch.. Also I would like to build a 42" oven but it will be a tight sqeeze. Could I wrap the lower part with Insulfrax until I get clearance and the switch to vermiculite?

    We had a discussion about AAC:

    I don't think anyone has used it yet, but I think it has a lot of potential. You might not even need vermiculite concrete. Keep us posted about what you do.

      Goodmanheat,

      Why don't you just wrap the entire oven in 3-4" of Insulfrax, and forgo the vermiculite all together. That will definitely stop the heat, and it is more space efficient.

      I made a posting a while ago about solid-state ovens, and I am increasing being drawn to that design. The cost of the high-tech insulation is coming down, and it is lighter, easier to use and takes up less space. Insulfrax above and SuperIsol below.

      Also, that is how the Modena ovens are made -- and they are awesome.

      Whadya think?

        James,

        If just using the Insulfrax do you then put the stucco straight onto the insulation? or do you suggest putting wire over the insulation first before applying stucco? Thanks,

        Simon

          I think you still need to give your Igloo shape. You can do that with either stucco (pencil) rebar and lathe, or plain old rebar and lathe. Then you do a rough coat of stucco on that, and then your finish coat.

          You don't build up for the vermiculite concrete this way.

          We use rebar to build the Toscana Igloos.
