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.

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!

  • will this support a brick chimney?

    I'm starting to lean heavily towards building a brick chimney whereas I had planned to have a simple SS flue sticking out the top of my oven. Please see attached pics. I need to pour a small concrete beam to fill the gap in the attached image between the brick arch and the flue. I'm considering the following to support a brick chimney, probably a max of 4 or 5 courses high + a cap I'll cast myself:
    If I pour a concrete slab to fill the gap behind the arch and extend it over the top of the oven and around the flue, spreading out around the chimney about 150mm and resting on the vermicrete will the vermicrete layer provide enough support behind the flue area to build the brick chimney on it?
    I'm hoping by spreading the load the vermicrete would be able to take the weight. I dont want to have to damage the existing insulation as it performs really well.

    I am a little confused about the gap in your pic. But, if you place some plastic over your vcrete (to keep from adding more mosture to your insulation), and make a suitable reinforced form, you should be ok.

    Over kill, I know, but this the way. that I did it.

      Thanks Gulf, that's a beautiful job on your chimney. Lovely workmanship! Well done. Its a high looking chimney!
      My oven is a kit and the entrance arch came as a 3 piece section. I slid the top piece tight to the dome to avoid a gap resulting in that small gap at the front.
