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!

  • 6" insulation under dome?

    I wanted at least 4" of cal sil under the dome, and got two boxes in 1.5" thick boards. Any reason to go over 4.5"? I have enough boards for 6", but I'm concerned about settling under the dome with that much (I think Lee encountered that) and suspect there's a law of diminishing returns after 4.5" of insulation under the dome. Any point to 6"?
    Here's mine:

    Re: 6" insulation under dome?

    I am about to close my dome and have four inches of cal sil under my floor. It seems like a lot but I wanted to make it as well insulated as I could. Plus I got the skamol board fairly cheap and sorta close to my home.

    I don't think you would have settling or any compression of the board. It is pretty strong stuff compression wise. I am not sure if you would need more than four and a half inches. I am using my left over board to make an insulated door or two.

    Good luck with the build.

      I have 2.5 vermicrete and 2 FB board and I still see a small rise in temp through the floor after a long burn, We had an afternoon neighborhood party where I kept the oven at over 800 for 5-6 hours, the wood storage bin ceiling got to about 130 at hour 5 with an ambient temp of 80 so there is some heat being lost via the floor. I did not take regular measurements.. I guess I could have added more vermicrete....
