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!

    ok, Im starting my earth oven/clay oven/adobe oven. not up on all the terminology. after i build my sand form. what is the next layer? I know not to put straw in this mix, but what is this mix, made of? just portland and clay? or portland/clay and sand? should I use any refractory mortar anywhere? if so, where? can I coat the finished project with a parging stucco
    (sand and mortar?) . I will have an overhead roof to protect the whole structure. the only firebrick I will use is the oven floor.

    ty all

    I would sugest that you look at " other oven types" down below in this forum. There are several folks building "cob" ovens. Also see thhttp://www.fornobravo.com/forum/f6/rustic-primitive-materials-18543.htmlis thread

        You can use a little straw in the mix as reinforcement of the cob mix. Being unfired clay will have considerable shrinkage so remove the sand mould about 24 hrs after finishing the initial layer, otherwise you'll get shrinkage cracks. A mix of straw with just enough slip (clay and water mixed to pouring cream consistency) makes an excellent insulator, but don't apply it until the inner layer has dried. When it looks dry it won't be inside the clay walls so proceed with caution.

          I know Ontario is a large province but we got through Dryden each year for a fishing trip. If you are any where near there I would love to stop and see your oven, mine is always available for visitors and with some advance notice dinner can be served.

            heya chip.. nope im a long way from dryden.. i have been thru there many times and loved it.. great fishing. I,m just west of sudbury.(50 miles) home of the 5lb mosquito and the 10lb deerfly.. you dont wanna know where the deerfly bit me yesterday, as i was working outside in my underwear.

            I have been thru minnesota a few times.. passing thru on my way to BC. beautiful country and folks always are friendly to me. I live kinda remote and rustic here.. small cabin.. no running water.. but I finally got hydro and internet.. never had a use for TV.

            an oven would save me alot on propane. wood is free.
