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!

  • Curing Cracks

    So, I guess my second fire went a bit too hot (or the fire went too high because it touched the top of the dome). I wound up getting those 1/32" cracks around the dome in various places. I can't see them from the inside. So far I assume it will be OK once I cover with blanket.

    My question is, suppose I can see a crack from the inside. What would I do in that case? Are the cracks a major issue, or does it just mean that insulation will be even more important?

    Thanks!

    It's a rare oven that doesn't have hairline cracks. The oven moves everytime it heats up, and cools down, and masonry is inherently brittle. The good news is that we've never heard of a pompeii style oven that collapsed.

      That's good. I can't see any cracks inside the oven still, but the crack ended up going around the oven in a complete circle (although not all on the same course). That actually had me pretty concerned. I will look close tomorrow when I can stick my head back in. I thought I saw steam (or smoke) coming out of one, but it is not very wide so I don't think it is from the inside of the oven... if that even makes sense.

      Nothing is movable though. Maybe cracks are not all that bad! That's what I am going to tell myself all night.

        Jared,

        You probably saw steam coming out the cracks. Your oven is still wet from construction (and will be for a few more fires).

        I also have those hairline cracks that circle the entire dome. They don't cause any problems.

        Take a picture of your cracks and post it. We all love comparing our cracks and consoling one another.
