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!

  • "White oven" design

    Does anybody have plans for a "white oven"? It's a barrel style bread oven where the fire is made underneath and not inside the oven.

    Other than large commercial ovens for commercial bakery use, the only "white" ovens for domestic use that I know of are built as part of a masonry heater.

    Try the Masonry Heater Association for more information

      Thank you very much, I found all the info I needed except for one more stupid question: How do you make a reinforced refractory slab as the base of the oven? I assume it's made from fire cement, but what do you reinforce it with?

        In our ovens, we make the support slab out of ordinary reinforced portland cement concrete, and this supports the weight of the oven, which is insulated top and bottom. I don't know what they do with the masonry heaters. I'd guess that the floor of the oven was the flat top of a firebrick arch which is self supporting, but I don't know enough about the subject to say for sure.

          Thanks. Most of the designs I saw uses a precast slab as the hearth floor. In the "white" oven, the base(hearth) of the oven sits directly above the fireplace, with the air flowing underneath and around or behind the oven. What I don't know is how much heat can this base stand without cracking. What do I make it from, how thick, and how is it reinforced? I assumed reinforcing it with metal is out of the question since the metal might expand faster than the concrete.

            Places that sell, and places that make refractory concrete have engineers on staff that can answer your questions about refractory concrete. This in not something you can buy at a home center: The refractory dealers will know a lot more than I do, and even more info can be had from the manufacturers, like Harbison-Walker.
