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!

Dome Installation Video - Casa / Premio / Modena


For many of you who bought a modular oven, you may have asked how we put the domes together when we build them. For those of you considering one of our ovens, we shot a video to make your install easier.

Check it out on our You Tube Channel.


If the link doesn't work, simply go to You Tube and type Forno Bravo Channel. The video title is How to Set your Forno Bravo Oven Dome Pieces.

Thanks for participating in our Forum. We will have more video content available soon.

  • excess cement on outside of dome.

    Should I or shouldn't I be spreading the extra cement over the outside of the dome? Am I supposed to spread a thin coat over the whole exterior when it is completed anyway? The dome is not going to be seen when completed.

    Don't put cement on. Generally a 1/2 inch or so of mortar (or even concrete) is spread on.

      Do you use the same mortar as I am using for laying up the dome.
      The homemade fireclay mix?
      Then after the dome is done, and I wrap it in the blanket of insulation, what mix do I use over top of the insulation?

        You don't need to add any mortar to the outside of your dome. Pompeii ovens, when built with half bricks according to the plans have plenty of thermal mass. They have much more mass than any of the kits. Some people add a thin layer in an attempt to strengthen the structure. I don't think it's necessary. Cracks will happen whether or not you add the mortar. The extra layer will certainly not make the difference of whether your dome will remain standing or collapse.

          I used about 1/2" of the HeatStop 50 that I had used for the build, kind of costly, but I had a 1 1/2 bags left over. I figured it wouldn't hurt a thing and it gave me a smooth uniform surface (which I really didn't need) before the next step of blanket and chicken wire. For me, it just made the oven more complete looking for that week, as I didn't proceed until the following weekend.
          Totally unnecessary, but alot of us have done it.

            I put extra mortar on the outside of the dome mostly because it helped keep the bricks in place better (when I was mortaring them on). When they get vertical it really helped them stick. It wasn't a lot but just enough to give it an extra connection.

              I also put the extra mortar because i found it helped keep bricks in place when building.. same as Mike D..

              Plus it looked nicer during construction.
