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!

  • Unpolished/Sealed Granite

    Anyone using unpolished/unsealed granite as a cooking surface? I got a great slab for free and would like to use it. I saw one short post in the archives that recommended against this because of granite's inability to absorb moisture. However, I'm not sure if there would be the same problems with unpolished/unsealed granite and would really like to hear from anyone who has actually tried this.

    Also, any direction on installing FB Board? Do I just lay it down on the structural slab? Didn't receive any directions with the materials.

    Thanks.

    Re: Unpolished/Sealed Granite

    Hey, welcome. The granite cooking floor question has been asked, and it was thought that the surface might be subject to chipping when exposed to direct flame (google flame finishing), but to the best of my knowledge, no one has actually tried it. Please let us know if you do.

    If your structural slab is flat, there is no problem laying down the Cal-sil boards directly on top of it, and the floor on top of that. If it's not flat, you may need a thin layer of sand and fireclay to level the surface.

      If you pass a torch over granite it will pop and scale so it is not a good choice but you may be able to use soapstone..

        Thanks for your comments. I fire tested a sample of the granite in my smoker/BBQ....after having the sample in the fire box for a couple of routine grillings, I got the temp up to around 550 this weekend and kept it there for about 45 min or so as I roasted a standing rib roast (and then down to about 325 or so for another hour). After it all cooled down, I was able to break the granite with my hands and w/out much force....so, looks like we have a nice backyard table, but no hearth/cooking surface. Back to the drawing board.
