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!

  • Two holes (not cracks) leaking smoke: mortar or furnace cement?

    After building my second drying fire, I discovered that there are two areas near the vent that I did not seal, and are leaking smoke. I need to patch them. One is a hole 1" in diameter; the other is a narrow strip about 1" wide and 18" long, between the vent manifold and the brick arch in front of it. The brick arch is purely decorative, and is mortared to the front door bricks. But the top curved part is not mortared to the vent manifold, hence the gap. This was a building mistake on my part.

    I plan to patch the hole with a hunk of firebrick. For the narrow strip, I can probably wedge in some firebrick strips leftover from building the dome. The question is, do I need to use fireclay mortar or furnace cement? I want to avoid using mortar because it will take longer to dry and cure before I can continue building drying fires.

    Thanks,

    - Fio
    There is nothing quite so satisfying as drinking a cold beer, while tending a hot fire, in an oven that you built yourself, and making the best pizza that your friends have ever had.

    Fio,

    Not absoltely sure without being on the spot, but I think furnace cement should work just fine, so long as it's not a working part of the oven interior.
