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!

  • Perlite Insulation Board

    Hello,
    I have a friend who has some of this at his work and I might be able to get some for a decent price. Would this be acceptable to use under the floor as my insulation board? The only other purpose I can think of to use it as would be for the door? Or do you think I should stick with whats recommended.....Thanks

    I'd check around a bit about perlite insulation board - that's the roof insulation - right? I think it's made with some asphaltic compounds - so I don't know if it's appropriate to use as the insulating base for a wood fired oven. I also understand that there are some problems that have been reported with perlite insulation board and water absorption / retention - so do your homework . . .

      Re: Perlite Insulation Board

      I asked the same question years ago. It's mostly paper. Don't use it. There is some asphalt and a little perlite. It is not going to hold up to the weather and by no means the oven. Do you want to risk this stuff deteriorating and watch the structure fail?
      For the door...asphalt side out....ok maybe...when it fails you can just toss it but you still have to burn off the asphalt side. Sooooo, just don't do it. I thought about it and rejected the same...I had acess to free perlite board
