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!

  • Flat Stone Chimney Cap?

    I'd like to cap my 24"H chimney with some 1/2" thick slate I have, but I concerned about the heat degrading the stone. How hot are the gasses shooting out of that thing, and won't they destroy the stone pretty quickly?

    I'd like to lay the slate piece flat, about 4" above the top of the chimney.

    I saw Pizza Bob used a flat piece of stone, but it looks to be at least 2 inches thick. (link to his pic below)

    Any advice or experience is greatly appreciated - I'd like to cap it this weekend.

    I clocked the underside of the steel plate atop of my chimney with a laser.
    The plate is 1mm steel and it was about 120c with a roaring fire.
    The chimney is about 2.5M above the oven ceiling.

        Thanks for the reply - I capped it with a flat slate piece this weekend, and it ran about 300F when going full blast, so I think it will be alright.

        thanks for your pic of your cap - I like the simple approach.

        I actuall had a nice cap fabricated with a gabled roof, but it didn't look good once I put in on. not sure what to do with it.
