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!

  • High Heat Mortar Mix question

    Hello, I have conflicting formulas (by different dealers/people etc..)
    One mix is thi:
    1 part cement, i part fireclay
    another is:
    1 part cement, 1 part fireclay, 10-12 parts sand

    Seems like an awful big difference in mixes, or is it just me???

    Hi Frenchcanuck
    I have almost finished my Pompeii, only the final mosaic tiling to complete and I used a well tried and proven mix for my firebrick mortar, as 3 parts brick layers sand, 1 part hydrated lime, 1 part fireclay and 1 part portland cement.
    I have used it for 4 large cookups and no sign of problems.
    I certainly would NOT USE either of the formulas that you mentioned.
    I would recommend using a brickie sand rather than a washed concrete or plaster sand, but I don't know what you have vailable in your district.

    Hope this helps. I have a full pictorial build and explanation in the 'Brick oven photos' forum if you want to follow my construction.

    All the best with yours.

      Re: High Heat Mortar Mix question

      I concur with Neill. That is the exact formula I used for the barrel vaulted bread oven I constructed. It was a recipe I got through the grandson of a oven mason in Czechoslovakia. The only alteration I made was on the wall bricks where some people lay dry joints I used straight fireclay mixed with water. Other than that all joints are mortared with that recipe!
