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!

  • sand and clay under the firebrick floor

    Hi there,Forno bravians!
    What other material can be used instead of clay? As you don't recommend
    using mortar,would lime and sand be okay?
    Is there a special kind of clay that is required?
    Would plaster of paris mixed with sand do?
    As you can probably imagine not many Japanese are into the DIY oven building, the advice most commonly given is why don't you hire a contractor!
    In any case, your kind advice is really appreciated!

    Hello Masako, I have heard that you can use refractory cement like you would use to bond your fire bricks together.

      Hi Masako,

      I'm no authority on the topic but agree with toddj, and I am indeed intending to do just that. I am using a pre mixed fire cement which I have bought online. It comes in tubes and looks like it'll be very easy to use. I know your not over in the UK but to give you some indication as to what I mean go onto the website below and search for fire cement. This is stuff I have bought.

      Good look fella, Mark

        Masako,

        When you cut your floor bricks, save a few handfuls of the dust that is created. If you are using a wet saw, this will be a wet paste. Dry it out, by leaving it in a bucket. This is fireclay.

        Place the bricks right on top of your insulating layer. Sprinkle the dried fireclay as necessary under the bricks to level them and create a flat floor.

        Hope this helps!

            Works like a champ.

            If you aren't going to cut your floor bricks, pre-cut a dozen or so dome bricks in half. You'll have more than enough fireclay. I saved several sessions worth of the "mud". After it all dried out I had about 10 pounds of the stuff. Kind of a shame to throw it out, but I couldn't find a use for it all.
