did i use the wrong mix - 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!

  • did i use the wrong mix

    First, thanks for this forum -

    I downloaded the Pompeii instructions several months ago and started construction on a 1200 sqft fieldstone patio with oven last week.

    I poured the base last week for the Stone House oven and now realize that I may have used the wrong mix. I didn't use vermiculite - just regular concrete - is this a total screw up?? I plan on using the fireplace a lot - will it be okay to just use the firebricks on top of the reg. concrete??

    Hi Mini,

    Welcome aboard! I moved this to Getting Started. You should get more help here.

    The hearth under the wood oven has two layers. A concrete slab, that holds everything up, and on top of that, a layer of either vermiculite or FB Board insulation. The oven floor rests on top of that.

    If you follow the plans, I think you should be OK.

      Don't put the firebrick directly on regular concrete. You need some form of insulation, or you will lose all of your heat, resulting in a cold floor.
