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!

  • Time to cure hearth

    How long should I wait for rhe concrete hearth & perlite insulation mix to cure before I start installing the fire brick cooking surface. I live in the Puget Sound area & moisture,rain, can come at any time. I will be building a 36" Pompeii oven.

    hearth cure

    Jack, I think the primary wait in the cure for the hearth is for form removal - give it a week. For applying the firebrick hearth you're ok once it is firm - overnight should be ok depending on the concrete used. I kept my slab wet for several days with a wet blanket over it but that's really overkill - I did it primarily because I did not have the time for the hearth brick application right away.

    Are you starting to make progress or still planning?

      I think Maver has it right. Concrete takes a long time to fully cure, but you can start building on top of it when the top is firm, and take the forms off at your leisure.

      You will be in good shape curing the hearth while you are building the dome itself.

        Curing

        James, Maver,

        Agreed. The industry rule for concrete is thirty days for a full cure, but that doesn't mean you can't build on it while it's curing. I wouldn't do any firing for a month, though.
