How Large an oven can I get? - Forno Bravo Forum: The Wood-Fired Oven Community



I'm Peter Reinhart! Ask Me Anything! Monday, February 15, 2016 7:00-8:00 pm EST

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.

Ask Me Anything New Forum Feature

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.

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!

  • How Large an oven can I get?

    can I set a 42 inch diameter pompei oven on a 69" X 69" Base, or do I need to go to a 36 inch so I can insulate better?

    42" Dia. will work on 4 & 1/2 concrete blocks to a side

    (M)Hi, Steve, I wrote on an earlier thread which relates to insulation:

    (M) The most important first decision I had to make was whether I would enclose my Pompeii igloo with house walls made of cement board. I feel that this is so important an early decision that I am also going to post this message on the Newbie Forum.

    (M) The reason this 1st decision is so important is that when I decided to enclose my igloo (permitting me to add lots of perlite insulation under the roof) I realized that it would be a waste of time to do fine finish detail work that would ultimately be hidden. Paul and Robert are just two builders that opted for elegant detail. Robert with his mosaic, and Paul with his arched brick throat entry.

    (M) My recommendation to any Newbie is to make that 1st decision before you do any work! I struggled trying to reconcile different photos and directions until I realized that there is a fundamental structural process to be considered which is based on that 1st choice.
    (M) My hearth stand has 4 1/2 concrete blocks to a side and supports a 42 igloo. Because of how the courses are normally staggered there is no need to cut any blocks. The blocks are a nominal 8 x 16 inches but in reality they are slightly smaller to allow for a morter line.

    (M) If you want to see the initial construction phase of that stand, with comments on size, go to
