New Forno Bravo Forum Feature

Forno Bravo Forum Community,

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.

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.

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!

  • Brick Dome

    Hi All,
    I am working on my first proper oven. the first one I built burnt well, but wasn't well insulated enough. mark two is bigger, better and being built almost entirely from reclaimed materials.
    It has an internal diameter of 900mm. I have built the base and cut a fire brick floor to fit inside the circular walls. (Firebricks from old night storeage heaters). I am struggling to find a way to build the dome that I am capable of doing. i have two ideas.
    1. form a dome shape in pliable wire and then build over it.
    2. Step in each course of bricks by about a third of a bricks width so that it gradually goes in and will eventually meet. I could smooth over the "steps" with mortar if it is necessary.
    What do you experts think?
    Look forward to hearing from you.
    Cheers
    Nick. (Badsey, England.)

    Re: Brick Dome

    Having a smooth interior curve in actual firebrick material is worth the trouble, because the heat of the fire is reflected down from the fire, and radiated out from the hot bricks. We do this by tilting up each layer, or course, of bricks slightly, like 5/16 of an inch(8mm), on the outside. Experience shows that it's better to have excess mortar at the outside of the curve than on the inside where it runs the risk of chipping off from thermal shock and landing in your pizza.

    Also, your "step" plan puts the biggest steps on the top of the dome where the temperatures are the highest.
