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!

  • terracotta chimney installation

    First, I was wondering if there is a procedure for attaching a terracotta chimney to the vent (top of the transition part). Is high temp mortar used to attach the flue? Build up an area with bricks?

    Second, I would like to put stucco around the flue (like an "australian" style oven). Do the flue and the transition/vent get insulation blanket around them? It seems like this would be an extraordinarily hot area and I would think that expansion/contraction during cold seasons would crack the terracotta without insulation. I feel like the flue should be insulated somehow or is the air space generated from the chicken wire enough...

    Thanks in advance,

    Hi Sarah,
    The flue needs High temp mortar on all connections for sure. I unfortunately have no idea how you would stucco around the flue unless you enclosed it with steel studs and cement board first. You are correct with the thought of the flue getting hot! Even with my curing fires the flue gets all the heat exiting the oven. Building code around hear say to not have anything touching the flue, except for incidental mortar from and enclosure.

    I have built a chimney from a clay flue and surrounded it with cement block. I am worried about the weight being put on the vent/landing area with this amount of material. I will add brick above the roof line. I am planning on buttressing the sides of the vent/landing in hopes of preventing a collapse. See Dmun's build for the correct way to set up a clay flue.
    Hope this helps.

      You can wrap it it with blanket, then chicken wire and stucco over that. This will prevent cracks.
