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!

    Re: wondering

    Don't mortar the floor. Just set in on a bed of sand/fireclay.
    Check out my pictures here:

        You can mortar the floor, there is no issue other than your floor will be less prone to shifting.

        Edit-You do not even need to use refractory mortar, plain old mortar will hold up just fine.

          Hi Tomm,

          Most builders don't mortar the hearth bricks (floor). If you need to replace a bad brick or one gets chipped, how are you going to replace it if it is held fast with mortar?

          Mortar tends to get between bricks no matter how hard you try to keep them clean while setting them evenly, then gaps appear to mess up the others in sequence. Guess how I know this. Just fit the bricks as best you can without mortar and have faith that they won't shift. Heat expansion and subsequent cooling cycles move the bricks (and dome) around so it is a natural event.....embrace it.

            Experience has shown that a loose set floor prevents problems. An oven is always expanding, contracting, and in motion with each heat cycle. The reason the floor is laid without mortar, and the first course isn't mortared to the floor, is to allow for this thermal shifting.
