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!

  • concrete inside the oven?


    I will be building an oven sometime in the near future. I'm at the planning stage and I intend to do it as cheap as possible

    Here's my first 'very novice' question

    1. I can get copious amounts of used concrete paving slabs and concrete paving bricks. Is it OK to use this kinda thing inside the oven?

    TIA ... Mick

    Unfortunately, it's not going to work well.

    At the temperatures in our ovens, the portland cement breaks down and I expect an oven built with these materials will rain little bits of concrete on the pizzas... until it the day it simply falls apart.

    It would make a great material for the oven stand!!!

      Yeah, sounds like you have cheap stand materials! I'll second Christo's advice on not using concrete products inside the oven.

        There are several ovens built out of solid red housebricks, that'd be a less expensive way to go. Didn't mmmhumous build his oven like that? I seem to remember a discussion of red bricks somehwere in his build...

          Hi Mickfitz,
          I would not under any circumstances use cement bricks nor cement pavers or any cement products in an oven. I agree with Frances with using inexpensive or free solid red bricks as Russell Jeavons wrote a book on how to build an oven and cook in it using red house bricks. See my posting and the pictures of and in his commercially used wood fired ovens at permalink #16 at:


          I am to build another 2 ovens and help a friend with his planned oven using such materials. Keep the cement bricks etc for the stand and benches,as the oven will only be the start of a complete outdoor kitchen once you really get sucked into this recreational activity.

          Prevention is better than cure, - do it right the first time!

          The more I learn, the more I realise how little I know

            If you do use the concrete, please advise all forum members so we can immedietly run to our air raid shelters. That stuff will blow like no tomorrow with thermal shock and air bubbles expanding. DO NOT USE.
