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!

  • Recipe for lightweight strong oven base??

    Looking for recipe and ratios to mix vermiculite and concrete for a strong yet lighter oven base for which to put base cooking level brick then build dome oven on top from there.

    I've Heard it may be 5 to 1 ratio vermiculite to concrete

    You might want to clarify that question with a little more of an explaination of what you plan to build. 5 to 1 vcrete is recomended as an insulation layer for an oven floor. That is, if it is placed on top of a structural layer. It has plenty of "compressive strength", but no "tensil strength".

      Gulf has it right - you can't suspend a "vermicrete" floor on top of a U-shaped base.

        My vision is to Place the vermiculite and concrete Mix the base on this wooden structure. From this base I will layer of my firebrick base and then build up the firebrick dome
