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 Aluminium cement

    I have almost finished my oven
    I am up to the insulation I have used clay bricks and fireclay mortar inside and thermo blocks outside

    Now my work has giving me 4 x 50kg drums of High Aluminium cement Trade name Taycor 414FH 0-3 which are out of date (even though it doesn't really go out of date) they use it in high temp glass melter
    This stuff is used in metal forges able to get 4 x hoter than any pizza oven

    now my question is do I use it to line the inside of oven or keep it to make a mould of a future oven ?

    Regards
    Fred

    http://www.anhrefractories.com/produ..._HYDROCAST.pdf Well it looks like it could be cool. the link goes to a materials spec sheet. Says it is good for thin walled castings. I'd love to have a barrel of that myself, just to play with.

      Sounds like great stuff. It must have been pretty expensive. I wonder how thick they mean when they say "thin walled castings." It's 94% alumina and designed for 3000ºF. Hah, you could melt a pizza into glass at that temperature.

      I don't think you would want or need to line the inside of the oven -- your brick should a good job of retaining and storing heat for cooking. I think you can save it for another project.

        Re: High Aluminium cement may be too high

        (M) I'd be concerned about the difference in thermal expansion between a mortar of 94% alumina and bricks at about 30% alumina. I'm no engineer but it seems counter intuitive to have a cement with such different properties than the bricks it holds together. Remember that you are not going to be baking your pizza at 3000 degrees.

        (M)My 2 cents.

          Re: High Aluminium cement

          While I was researching castable refractories for my oven, Dave at ANH (Richmond, CA) told me that density is a good indicator of insulation properties. The 414FH is relatively high, so it will have relatively low insulation. This material is ideal for casting an oven, but I would not use it to line a brick oven. Concretes have about double the thermal coefficient of expansion of fire brick and will tear the brickoven apart from the inside. I second James, save it for the next project.

            Thanks for the replies
            I will keep it for an other project as I have already cooked my first pizza in the oven and the bricks were fine without the High Aluminium cement
