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!

  • Isol blanket !

    How many sq.feet of this blanket would I need to cover my 31" dia. oven.
    does anyone know ?
    Would I have to wrap it around twice or once would be enough?

    Re: Isol blanket !

    Hi Masako.
    the area of your dome should be close to a half that of a spere, in your case the outside dimensions rather than using the inside 31" dimension. Add your wall thickness and do the following calculation"

    The surface area of a sphere of radius 'r' is given by:

    surface area = 4pr2

    NOTE: The value of p can never be known exactly, so surface areas of spheres cannot be calculated exactly. Common approximations for p are: 3.14, and 22/7.

    You normally get a specific area in a carton/package of insulating wool and this will vary from manufacturer to manufacturer and will vary again if it is 1" or 2" thick
    2" od superwool is the same equivalent as 4" vermiculite cement which is deemed as the minimum needed for a WFO. My 40" Pompeii has i" superwool and 3" vermiculite cement and when the oven is over 500˚C inside, the outside dome is cold.
