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!

  • Trying to build an oven in Ontario, Canada

    Hi there,
    I'm just starting on the firebrick for my build and thought I'd post here in the hope that the experienced and more knowledgeable oven peeps could advise (or assure) me before I do something stupid. I'm a little concerned because I have been reading about all the things that can go wrong, such as not heating up enough , or not holding heat etc. and I have made some modifications to the plans I started with from Alan Scott's bread builder book... trying to incorporate tips from other people's experience.
    So far I have poured a 6" hearth slab on top of my block base (not suspended it with rebar) and then poured 2" of Kast-O-Lite insulated refractory on top of the slab to hopefully keep the heat in my hearth.
    My local refractory supplier suggested setting the hearth brick with the Kast-O-Lite but that proved impossible as it hardened on contact and I couldn't level the bricks. After several unsuccessful attempts, I mixed a fireclay/portland/sand mortar and laid the brick on the flat instead of on end. They are finally stuck down and level.
    Will the hearth be too thin laid flat? I am toying with the idea of pouring an inch or two of Uni-Cast 70 for a nice smooth, level cooking surface, but I'm afraid of it cracking. It seems that some have successfully done this in sections or by scoring the slab to control the cracks.
    Any advice or feedback (or assurance!) would be greatly appreciated before I continue. The photo shows my progress so far. Sorry for the long post
Working...
