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!

  • Insulation Question

    Hi all.
    Getting ready to start construction soon, but have one question pivotalto everything else. I am looking to build a 42 inch diameter low vault pompei oven and need to know exactly how big to make my hearth and base. My oven will be 42 inch internal diameter (give or take the size a few inches with brick size variances where I am) and would like to know how much insulation I need. On top of the brick walls, is 1 inch insulfrax insulating blanket plus 4 inches vermiculite insulation enough? Does covering the finished dome in mortar before insulating help? I will then render the outside layer for appearance. Will this give me enough insulation for pizzas and for a few bread bakes or at least one?

    Any thoughts would be a huge help.
    Cheers

    Yes, that's plenty of insulation. Remember you need an inch or so for your finish stucco if you are doing a dome type finish.

    Does covering the finished dome in mortar before insulating help? Will this give me enough insulation for pizzas and for a few bread bakes or at least one?
    Covering the brick dome with masonry will increase thermal mass, and increase the retained heat, and also absorb more heat, taking longer bigger fires to heat up. It has no effect on the insulation. Consensus seems to be that the half-brick thickness of the pompeii is more than enough.
