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!

  • ceramic insulation "bricks"? "Skagits"

    Hi,

    I have finally found a local supply, (near Vancouver), of calcium-magnesium cilicate (CMS), insulation, but it comes in full brick dimensions, not a board.

    Any thoughts or experience on performance and handling I should be aware of?

    I have also found some 12"x24" "skagits", that are 2" firebrick tiles for the hearth,... very cool.

    I am now just about to start the 42" build. This will be my 2nd oven. Really looking forward to this and will post pics soon. Thanks to all on this forum for helping with far too many design and building ideas.

    The topic of insulating bricks was recently covered here:

    I think the reason most builders go with vermicrete or board (or a combination of both) over insulating brick is the cost.

      I used the Insulating Bricks under my Firebrick floor...they are 3" thick and came out of a furnace. I used them because I found them on craigslist cheap ($1 each 3x7x9). They are an industrial insulating product, and they were easy to work with.

        Cal-sil bricks? That's a new on on me. Cal-sil board is considerably more expensive than the mineral fiber types, it may pay to shop around.

          The cal-sil insulating bricks are widely used by potters in kiln building.

            Hi,
            Thanks for the comments.

            The insulating firebricks (IFBs), are cal-sil, the name is Iso-Perlor. Maximum operating temp is 1652F, and crushing strength lb/sq" is 290.

            They cost $3.50 CA each. This has been my best option, other than vermicrete. I used vermicrete for my 1st build, and am looking for better performance for this current project.
