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!

  • Refractory Bricks

    I am ready to start the dome construction, but I am feeling a little uneasy about my refractory bricks. I bought them many years ago from a demolition of a glass blowing kiln. I have no idea how to determine if they are appropriate for an oven. They were manufactured Royal Gorge--I can't find any info about the company. Due to budget constraints I am hoping they are OK. Any thoughts? Also, what is the estimated amount of bricks for a tuscan style 36" oven?

    Hi Marty,

    How much do they weigh and how large are they. A typical medium duty firebrick weighs about 8 lbs, so if your weight and size are consistent, you probably have the right density.

    I think it would be hard to tell the duty rating on the bricks -- which depends on the composition, but really, you will be fine regardless. Medium duty is optimal, but even high duty bricks are OK. They get really hot and cool down a little faster, but your oven would still be fine.

    You need about 180 bricks for the floor, dome and vent.
    Enjoy!

      Would there be a concern if they were used in a glass kiln? I don't know if brick can absorb the lead or not. Just a thought.

        I hadn't thought about the lead. I should probably look into that. The bricks are standard size 9 x 4.5 x 2.5 and weigh 7.5 lbs.

          I will think about who to ask about glass and lead and get back to you. Otherwise, your bricks are looking good.

            I sent for a lead test kit from Lead Check. LeadCheck Swabs Industrial. I contacted several testing labs and they all expressed concern because lead becomes volatile at the oven temperatures. They also thought I should test the clay I will be using for mortar. Hopefully the tests will be negative and I can get on with this project.
