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!

  • D70 fire brick

    i have located some free used firebrick. they are 4.5 x 9 x 3 and have d 70 embossed on them. does anybody know what this means? also they have been outside uncovered for 15 years. i live in central canada and can get cold -30 f. to +100 f. does anyone know if they are they worth using?

    I think you have a duralite 70 firbrick manufactured by Chicago Firebrick - no longer in business. This is a 70 % alumina brick that is around 160 pcf. THese brick will take a long time to heat up, and a long time to cool down

      Nothing beats free. These are high-duty expensive bricks, and I wouldn't advise anyone to go out and buy them, but they will work fine. They are just a little harder to cut than the ones from the brickyard.

      Good luck with your project - keep us posted.

        thanks for the speedy replies. i have completed the hearth slab and hope to start on the brick hearth next month. i bought new low duty firebrick for the hearth and i think i will use the D 70 for the rest of the oven. thanks again for your help.
