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.

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!

  • Help me replicate this 1847 oven design

    Hi all!

    A while back I posted some photos of brick ovens built at Port Arthur, Tasmania, which was a convict settlement/prison. I went back earlier this year and have been looking through my photos of this one oven that I would love to recreate (as I think I need to build a second oven in the back yard)

    I have attached some pics and dimensions as far as I can figure them out. Love to hear any advice on how to build this - the layout is straight forward, a rectangular oven with rough arched roof and tapered entry. I am interested in this design because it is so small, and I'd love to have something I can fire up more quickly for small family meals and a few loaves, as opposed to the big pizza monster.

    My main questions are - what kind of buttressing might be needed to support those walls, assuming they are single brick?
    And how would you go about building the arch - maybe that ties into the wall buttresses?
    Also any other advice appreciated!

    The design in your attachment looks very much like an "Alan Scott" style barrel vault design. Do an internet search for "Black Oven" and you should find a link with several pictures of a simularly built oven. I believe the web address is blackoven.idkhosting or some such thing. Good luck

      Wow Tim;

      that is an interesting oven. Extremely low ceiling, which looks like it is just hanging there. I'd say it was built with a sand mold though the difficult would be building that ceiling without it falling in given how flat it is. Are they standard sized bricks?

        I measured the bricks against my hand, they seem to be 190mm or so on the longest side and normal 2:3 ratio. The bricks were actually made on site with local clay; I saw one of the wooden brick molds they used in a display there. Next time I go back, I'm taking a tape measure

        It definitely looks unstable doesn't it! But that roof has been hanging there for 163 years stuck together with nothing but crumbling lime mortar.

        Cheers for the tip Polo!

          It seems like a pretty standard 27 by 30 inch barrel vault oven. At least the convicts had the good sense to alternate the bricks in the arch, unlike the Scot system. I like the iron door frame, which presumably had a door hinged to those two pins. If your budget will stretch to some blacksmith work, I'd definitely try to duplicate that. I also think the stone lintel in the outer arch is slick.

          And of course you're not going to try to duplicate old materials: I'd advocate modern brick and insulation all 'round. Don't be so quick to condemn the old lime mortars. They are said to be flexible, and might actually prevent cracking in an oven instalation

            Yeah it's a nice design! I was amazed to see so many brick ovens there - every house had one, and most of the other buildings too. Some much smaller than this one, strangely.

            I think modern materials are the way to go for sure, but lime mortar has interested me for a while. It might be good to give it a go for this build.
