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!

  • Yet another firebrick question!

    Hi All,
    I have come across some second hand firebricks at a brickyard. Are there any issues with using used firebricks that I need to bear in mind when purchasing, other than making sure they are 'structurally sound'?

    Does it matter what the bricks came out of? Could they have 'absorbed' any chemicals as part of their previous life?

    Any advice appreciated.

    Cheerio,

    Mark

      You have nothing to worry about except heavy metals. If they came out of a blast furnace or smelter you might have a problem. Most used firebrick came out of ordinary boilers and should be fine.

        Thanks Fireandflames,

        The guy just said they were from a 'kiln' so I'm not really sure. I would think that they should be OK but thought that those with greater knowledge than mine could provide some advice!

        Cheerio,

          Remember that for your dome you will likely cut a new face for all the bricks you will see (most anyway) so the old firebrick faces can all be buried in the dome mass. I bought new bricks for the hearth floor and will recycle old bricks for the dome and insulation layers.

            Modern kilns are made from insulating firebrick. If the bricks are light, porous, and easily dented, they are good for insulation, not for your dome or cooking floor.
