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!

  • Hearth slab pour - problem - not adhering to cement backer board base?

    Hello,

    I just poured my hearth slab yesterday. I used a pretty flat surfaced cement board as a bottom base (instead of plywood) for the concrete.

    I took an end form off and it looks like the concrete did not adhere to the board. Did I jump the shark in my concrete mix/pour? The day turned into a pretty hot one (after a cold spring, who'd have guessed the temp would soar to near 90?). I did pool water on top of it after it set to keep it cool/moist.

    The hearth slab and base are pretty heavily rebarred.

    And upon further inspection, note to self - the cement board I'm using has a rough side and a smooth side. The smooth side is as smooth as a baby's you know what.

    If I want mortar or cement to stick to it, use the rough side not the smooth side.

    Meh. Maybe I can recycle some of it for the enclosure.

      I dont think itll be a problem as the cement sheet or ply is only there as form work, once set the slab should be self supporting.
