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!

    I've heard it can take a couple days to fully cure and even then the stuff is spongy like cork. What was your cement to vermiculite ratio?

      Thanks for that MK1 it seems to be getting better now 24 hrs later i am glad you said about the being like cork.

      P.s wish i had have known that. i did not sleep last night stressing about what i did wrong. My mix was 5-1.

      I wonder why the whole lot will not crack once i have finished it if its going to be like cork.

      Thanks all

        Some people (experienced) use even less portland cement, so yours will bear the weight. Don't get on it too soon. I'm just now pouring the hearth slab today so I've never used it, but your question has come up many times and I've read about half of everything on this forum. Do a search.
        I have investigated the design James and help has put forth. It is very well thought out, and better yet field tested. We owe them.

          Keep it damp for at least 7 days.
