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!

  • Brick Content Issue - alumina safety etc

    I'm considering building a brick oven and have some questions from some of the people that may be using the oven for baking/pizza.

    As if there isn't enough food additive & safety concerns w/ ingredients & metal pans, some people have questions the safe of alumina in the fire bricks.

    Is there an issue w/ alumina in the same way that people are concern about baking in uncoated aluminum? Are they related elements/chemicals?

    Is alumina is baking stones/tiles? Naturally occurring clay?

    Brick Content

    Just my opinion.. I just looked at a MSDS (material safety data sheet) for Alumina and to me it looks like some pretty docile stuff. Especially in it's non-friable form locked in the firebrick. Do a websearch for "MSDS Alumina" and you will be able to download the sheet.

      Alumina in firebricks is different stuff then the aluminum in pots & pans. It's a stable compound and is there to enhance the conductivity of the firebricks -- too much though and it gets brittle. So we go for low or medium duty firebrick with an alumina content somewhere south of 30%.

      There's been some discussion of the health issues of alumina in firebrick in the Yahoo brick-oven group. But with everything else that's more provably harmful, no one I know in the brick oven arena is worried about the aluminum in the brick.
