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!

    You have to insulate under your floor to avoid heat conducting down.

          Hi Food&Fish,

          You need to insulate under the hearth.

          Can you send a few photos of the project with enough detail for us to review and recommend a solution?

          Without more information, I will assume you will be working within the confines of the oven dome. It is possible to do a good job retrofitting the oven with insulation and hearth if you plan ahead and make the necessary tools or construction aides for leveling the insulation and placing fire bricks. Your project is challenging but will be satisfying when completed.

            Re: new floor

            If your oven is uninsulated, removing the floor and putting in a two inch layer of refractory insulation board under the floor will greatly improve things, but if your dome is sitting on the bare concrete there is still going to be a huge heat leak from the thermal bridging. You also have the issue of raising the floor: this will reduce your oven and door height.

              Re: new floor

              Is there a reason you originally went for so much mass in your floor(3" fire bricks + 1.5" tiles = 4.5", a full two inches over the standard 2.5")?

              If you can find some 2.5" fire bricks in place of the 3" you have you could use 2" of ceramic board insulation and end up with the floor exactly where it is now and the ratios unaffected. If not you can still use 2" of board and your 3" bricks and only be half an inch higher which shouldn't effect the function of the oven.
