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!

  • wood for the base?

    to save time and money I was thinking of supporting the hearth slab with a framework of salttreated 6x6s. Think there would be any heat/combustion problem? the rebar coming out of the slab would rest of the 6x6s but could they transfer enough heat to matter if it was wood??? thanks, bruce

    Wood bases are not recommended. Wood is flexible, and masonry is heavy and rigid. A rigid support will help you avoid cracks. It's not a heat transfer problem, as the bottom of the support slab barely gets warm if your insulation is working right.

      Re: wood for the base?

      I used a wood base for time, money, weight, reuse and sustainability reasons, but it was for a clay oven. Quite a few people build clay ovens over a wood base, but I wouldn't do so if I was building a brick oven. Like dmun says, there's potential movement which will cause cracks.

        Clay/wood - no prob.
        Brick/wood - er, I dunno... Dmun is right - masonry isn't very forgiving. But on the other hand, a floating base (no direct linkage between hearth and floor) shouldn't have that problem as long as it's contained (floating off the edge would be a bad thing... )

        I'm not sure you'd actually be saving much in the way of time (money would depend on sourcing). Even a wood base needs a foundation and laying block on a foundation isn't likely to take that much more time - especially not if you're using carriage bolts. (You could cheat with block and only do two walls as long as you reinforce them.)
