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!

  • Hearth insulation query

    Hi,

    My name is Shane and I have just started curing my new oven. Unfortunately it is not a Forno Bravo as I found it hard to find someone in my area (Western Australia). I found another company that I found to be excellent and have just completed a great install. I managed to build the base but had the manufacturer complete the construction of the oven. Today I managed a larger fire than I have over the last three days and noticed that there was heat on the underside of my slab. I could manage to hold my hand against the tin but only for about 20 seconds before it became intolerable. The slab is approximately 100mm thick. The manufacturer installed a ceramic insulation matt and then the hearth went on top of that. My concern is that the concrete may be getting too hot. Is this a concern? And what is the maximum temp that concrete can sustain before I should be concerned?

    Any help here would be appreciated.

    P.S. I have also been known to be a worry wart so feel free to let me know if I am over reacting.
