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!

    Another one of my wild thoughts....
    What about an upturned cast iron bath for the oven, then cover with mass of some sort like gravel, broken bricks, then insulation?

    Just cut the bath off to length then build the front arch etc as normal.
    The baths are available from Epay for about $200.

    You could even get a white one so the dome is always white...


    The enamel according to wikiP doesnt melt until between 750 and 850 C

    The enamel won't melt but it will probably crack and fall off but... you can also get scarey close to the temps you quote in the dome!

    It would work better for pizza than bread because pizza doesn't particularly depend on retained heat other than the hearth. While one could certainly bake bread in it, the loose gravel/whatever would not be likely to store or conduct heat nearly as efficiently as solid refractory (but coating it with refractory won't work for the thermal expansion will break the refractory up.

    Try it and report back!

      I'd be a little concerned about the lead content of old enamel.

        Just one question.....

        What are you smoking/eating to conjure these ideas?

        Never hurts to think outside the box. If you want a readymade oven, the end of a large propane tank sounds good. Somebody posted about it recently.

        Stay dry Brickie, and trim the vegetation around your house to retard the next roaming fire

        I buried one of those tubs in my yard, you can have it for free, just stop buy and I'll help you dig it up. It was slightly used however

        My best to you.

        I try to learn from my mistakes, and from yours when you give me a heads up.

          Ive always had "these" thoughts, and think it strange that others dont....

          Never hurts to put it out there.

              Aw, Brickie! You're just trying to lure some unsuspecting lout into building your "nightmare" and saving you the time and trouble! )

              More seriously, I think it would/could work pretty well for pizza though dmun's comment on lead is well conceived.

                  This has been proposed before:

                  http://www.fornobravo.com/forum/f3/c...oven-8640.html

                  As for "flaking off" of the enamel I suspect not, rather more likely to bubble and get ugly looking. As for expansion cracking an externally added thermal mass: this shouldn't be a problem if one accounts for it in the construction. My WFO has a steel interior and I made provisions for expansion and contraction and have had no problems with this.

                  The "Tuscan Grills" are cast iron as are alot of the gratings in furnaces and grills in quality BBQs. Cast iron is actually quite stable in the temps we are normally working.

                        Hey....if you have a bathtub, make an oven, and if the enamel flakes, and cracks, just burn it off with high firings. Bare cast iron would be ok.

                        Old ovens were made of anything available. Add some scrap steei to Tman1's oven, insulate, and go. Take Dmuns geodesic shapes and cast them in iron....with a system to clip them together...and go.....this is like Mechanics Illustrated magazines just after WW2!
