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!

  • Using Limestone for oven floor

    My friend has a granite shop and has a piece of Grayish Limestone he had left over from a countertop 1 1/4" thickness and 4ftx4ft. I can have him cut to specs, but want to know if using this as the surface and using insulating firebricks underneath would be good enough without issues. Do I need to treat the limestone in any way?

    thanks in adance

    You need to not use it for the floor of your oven.

      The crystal structure of limestone isn't stable under the heat that WFOs get into. You'll be fighting it falling apart in short order.

      Sorry.

            Limestone, wherever you incoorporate it, is going to wear easily and produce a powdery surface with use....unless it has turned to dolomitic limestone, which is a bit harder.

                While soapstone does absorb and hold heat well, the reviews are mixed on soapstone on the oven floor. Here is a good informational link on the subject. Keep searching, your friend will have something you need

                  Yes, you can give any shape to limestone tiles because these are flexible. You can use limestone tiles on flooring, countertops and walls.
