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!

  • Dome insulation mix

    Hi All,
    I'm about to start insulating my dome and was wondering what mix of cement/vermiculite experienced builders would recommend. I seem to remember 1:11 or 1: 12 ratios at some stage but would just like to confirm.

    Do a search on the forum and you'll get all the info you want. Basically the more cement you use the stronger the mix will be, but the less insulating it will become. It is all a matter of the density of the resultant mixture.
    Kindled with zeal and fired with passion.

      Thanks david,
      I did a small trial mix of about 1:12 last night (Australian time!)and by this morning to was pretty firm. I think the 1:11-1:12 ratios should be fine as there is no requirement for strength in this layer. I also take your point about more cement = less insulation.
