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!

  • Looking For Advice Re Oven Floor Insulation

    hi guys,
    im new to the forum but im being reading a lot lately looking for tips and learning different methods to build ovens..

    i already started building my oven and need some advice for the insulation of the floor..

    my first idea was to just use a layer of glass and rock sea salt and on top of it another layer of refractory mortar..
    then on top of it would place the alumina bricks...

    although now i bought the ceramic fiber blankets to insulate the dome and since i have spare i was wondering if i should also add one layer of ceramic fiber on top of the rock sea salt... to add extra insulation...

    so basically my question is if i should just go with
    glass/rock sea salt/refractory mortar/alumina bricks

    or
    glass/rock sea salt/ ceramic/refractory mortar/alumina bricks.

    what would you recommend?

    thanks in advance for your help.

    Don't put salt anywhere in or near concrete. It is corrosive and will do little as insulation.

    Glass is not a great insulator either...but it's better than putting the brick in contact with the concrete slab.

    Go the standard perlite/vermiculite concrete mix or ceramic board.

      thanks for your reply.

      the problem i have is that materials are really hard to find down here..
      i had to order most of the materials from manila..
      so i cannot get perlite/vermiculite or ceramic board... although i have the ceramic blanket..

      should i use the ceramic blanket on top of the glass then?
      thanks.

        See if you can locate materials that davids suggested, in the other thread were you asked this same question.
