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!

  • Perlite or Vermiculite?

    Hi

    Are Perlite and Vermiculite interchangeable when building a bread oven?

    What is a reasonable price for a bag of Perlite or Vermiculite?

    Thanks again!

    Re: Perlite or Vermiculite?

    As long as you are getting coarse, yes they are pretty much interchangable, though vermiculite is much less dusty than pearlite!

    As for cost, depends on where you live. Here in the Phoenix AZ market, plan on $30+ for a 4 ft3 bag of vermiculite and $8 for a 3.5 ft3 bag of pearlite.

    Your milage may vary, all patents are pending, dont drink and drive - you might spill.

      I would suggest looking for a local hydroponics store. They will likely carry 8 cubic feet bags of perlite and vermiculite. I paid about $15 per bag. If you try to source these products at Home Depot or the equivalent, plan on paying a lot more.

        Hi, thanks for the advice.

        How many bags of Perlite or Vermiculite would you recommend to insulate under the floor and around the dome of a 80 x 80 cm Pompeii bread oven?
