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!

  • dome on vs around floor bricks & efficiency

    In the plans, it says that building the oven around the floor bricks is more efficient than if you put the dome on top. Can anyone explain why? I guess it's easier to build on top, so your cuts don't have to be as precise.
    Here's mine:

    Building around usually means you need to leave a gap - otherwise as the floor expands it'll push your walls outwards causing small cracks.

    No idea as to why one way is considered more efficient though... could be because the bricks in the floor would conduct heat outwards - so if you have an extra layer on the sides it'll then move upwards? Just a guess...

      Either way is fine.

      People on this site have built them both ways with equal success. They are equally efficient. The primary difference is:

      Outside:
      - You have to cut your floor bricks more precisely.
      - You may be able to remove and replace a damaged brick more easily. (This point is debatable)

      On top:
      - Maybe less (marginally less ?) outward expansion movement.

        If I build another oven I will place my dome on the floor. It seems like it would be easier.

        I placed my floor inside the dome on this oven. Just thought it was a nice look. I doubt mine will be more effcient than someone who built dome on floor. Given same the mass and insulation amounts I would think they would perform equally. But I have been known to be wrong before.

        It would also give one less chain to build.
