Air pockets - Forno Bravo Forum: The Wood-Fired Oven Community



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!

  • Air pockets

    Howdy All,
    I've just started construction of my dome (36") and have a question about air pockets.
    I'm using a very fine refractory mortar for the small joints lining the oven with the bricks held in place with shims (as per plans) then backfilling with a coarser refractory mortar that is designed for larger joints.
    I've tried to be very careful poking and prodding with my fingers to eliminate air pockets in the mortar, particulalry where the 2 mortars meet, but I'm a little worried that there may be some small ones in there that I obviously can't see.
    Are these going to cause me any issues later on or should I continue and not be too concerned about it. I figure that there will inherently be some air in the mortar anyway and I'm hopeful that the minor bubbles that I can't get out won't cause me any issues later on once we start to cook in the oven.

    Re: Air pockets

    The mortar is fairly porous so air pockets won't really be a problem although they do reduce the strength a little. Don't worry you'll be fine.
    Kindled with zeal and fired with passion.
