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!

  • mortar technique on fire brick dome

    Refractory mortar is supposed to be thin between
    fire bricks (1/8th inch); yet in all photos I've seen of
    brick domes in progress, the outer part of the joints
    seem larger with greater amounts of mortar used.
    Any advice on this?

    In a true refractory commercial setting you are probably correct. But many, many of these ovens have been built using wide joints (as you have noticed) and they seem to function just fine.
    Check out my pictures here:

      Les, thanks, especially for the Edison quotation.
      I will try to do as well as your photos. Just finishing
      the foundation for a Tuscan all brick exterior. A neighbor
      tells me, worry not, these things were made well by
      prehistoric people. Careme (a baker)

        With a good brick saw, does anyone cut the fire bricks for the dome such that
        the joints are pretty uniform? Any pictures of this?

          It does not get much better than Les's mortarless build. Also look at Gianni Foccacia's thread

            I cut all the firebricks for my 42" ID oven with a 4" grinder with a diamond wheel. It took 15 blades to make the cuts - It was tough but after 9 months of use(3 times min. per week) my mortar joints seem to be fine. The bigger and better saws would allow you the possibility to make more accurate cuts and use less mortar but in my opinion temperature change extremes are the worst enemy of WFO's. Lucky for me, here in Thailand, we don't experience that.
