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: fire clay vs heat stop

    Sure, you can use heat-stop. Put the powder down dry, just enough to cover the lumps in the vermiculite concrete, lay the brick floor, and when you're happy with how the floor is lying, wet the brick floor to set the concrete.

    The only advantage to the fireclay-sand mixture is that it's much cheaper than heat-stop.

      I didn't use any fireclay at all. I layed insulation board on the perlite/portland insulation hearth, and the board went on level. I just layed my bricks ontop of the boards.

          Mikipal, I ordered the FB Boards from Forno-Bravo. They are fantastic. Even though my perlite/portland hearth was rough on top, the boards went on nice and level. A perfect floor for the firebricks, and much better insulation than perlite/portland alone.

            I agree with Pizzajnky

            I put down a 3 1/2 of perlite base mainly to raise the hearth level then the 2 inch Isol board on top. Even with the Iso board I had to level the bricks a little. I couldn't imagine trying to put the bricks down on the perlite/concrete it was very uneven.

              I used Perlcrete.... then I poured about a 1 inch thick "slab" of high heat mortar on top. (poor man's)
              It was nice and level.

              But I love the idea of perlcrete followed by insulating board.
              An oven can never be insulated enough. IMHO
