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!

  • Maximizing heat from your outdoor fireplace

    I found this out by accident.

    You can double (or more) the heat from your fireplace by insulating the walls and using thicker firebrick.

    Here's how I found out. I have a ~5 foot wide outdoor fireplace. I had it lined with 1/2 thick firebricks. The firebricks weren't enough to protect the CMU from the heat and the CMUs stated cracking.

    To remedy the heat issue, I pulled out the splits, insulated with 1" KFAC-19, then put a layer of full size firebricks to line the fireplace.

    I had the fireplace in operation for one year in the old configuration so I have a pretty good gauge of the heat output. With the new configuration, I can honestly say there is a minimum of 2X the amount of heat output.

    Obviously I don't have any controlled tests of scientific before and after tests, but it is WAY hotter.

    I am guessing it is a combination of the almost zero heat loss through the sides and back combined with the heat retention of the full size bricks.

    Regardless, If you are building new, I would suggest spending a few extra bucks and insulating full bricks. The heat benefit and protection from potential problems down the road are way worth it.

    Regards,
