I'm Peter Reinhart! Ask Me Anything! Monday, February 15, 2016 7:00-8:00 pm EST

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.

Ask Me Anything New Forum Feature

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.

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!

  • Vermiculite / best Foundation Mix

    Hi All

    Ive built my main base for the oven --- have the firebricks ready for my 40ins
    pompeii oven..

    I would like to ask those who have experience what is the best mix for the vermiculite insulation for the base of the oven

    I have heard its
    5 vermiculite to 1 cement and 1 sand and should be 3 ins thick

    I have 2 large bags of a medium course vermiculit so Im ready to go

    If anyone who has built can advise it would be great

    Ta

    5 vermiculite
    1 portland cement
    No sand

    It's advised to mix it by hand, to keep the vermiculite from compressing. It will look and feel wierd, if you are used to regular concrete. Just dump it in, four inches deep, and gently pat it down on top with your trowel. It will harden up fine.

      Hi Ross,
      I echo Dmun's formula. That is exactly what I mixed for my 40" Pompeii.
      The complete build, including the vermiculite/cement mixing hint and pics are on the following post:

      http://www.fornobravo.com/forum/f8/n...-1-a-2005.html

      The whole build is in the Brick oven pics under Neill's Pompeii #$ and again in Neill's pompeii #10. Check them out, it might be of assistance to you. Feel free to email me direct for extra help if needed.

      Hope it helps.

      Regards

      Neill
