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!

    Hi All

    Will be getting a pre-cast dome shaped oven. The total size is 960mm diameter for the dome oven section. The oven with entrance area will be 1300mm long.
    If i do the suggested 4inch vermiculite/cement insulation, how many bags of vermiculite would i be needing? Roughly?
    The bags are 100ltr but ive never used it before so am trying to get an idea whether i should be pricing up 2 bags or 50!

    Well, if the supporting slab is 1300 x 1300 that is 130cm x130 cm x10 cm = 169 litres
    Two bags should do.
    Kindled with zeal and fired with passion.

      2 x 100 litres did roughly the same area for me..

      never hurts to get a bit extra, use the leftovers for gardens.. works great to retain water.

        It does compress a bit, get a bit more than you calculate you need. Note that the vermicrete insulation layer should only be under the footprint of your oven and not over the entire suspended slab. It should definitely not communicate with the weather as it would then be a source of water infiltration.

        Be sure to mix it gently by hand to avoid breaking down the individual particles.
