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!

  • stand size and foundation depth confusion

    Sorry for my first and very stupid question, but...
    I found that guidelines for corner installation described in "Pompeii Oven™ Plans" (page 15 to be exact, stand is 62x62" for 43" oven) differ of what is said on the other pages for standard installation (page 13, for example - 69" x 76" for 42").

    I'm going to get into 42-43" (corner inst.) story, so, what size of stand and foundation should I use?

    And another (I hardly hope not so stupid) question regarding depth of foundation.
    Soil frost line here (in Moscow) is about 60" (1.5 m), subterranean water level normally is about 90" (2.3 m), soil in my yard is so hard (on the depth of 40-60 cm) that it requires some special technic to dig it (heavy sand clay - I hope that I've used the right term).

    What is acceptable depth of foundation (gravel and concrete)?

    Thanks in advance,

    Re: stand size and foundation depth confusion

    For a 43 inch corner installation, the calculation goes:

    43 + 9 (I'm guessing your bricks are 4.5 inches wide - adjust this number as necessary to get the outside diameter of the brick dome) + 12 (6 inches insulation thickness) + two times the thickness of your planned finish material. If you use stucco, then just a couple of inches more. If you use framing, the something like 7 inches more. Somewhere around 72 inches on each side for a corner installation. If you use 3 inches of insulation blanket vs. vermiculite/concrete, you can scale it down six inches.

    An inch or so bigger or smaller on the oven size is not going to make a big difference in your capacity. You can kind of build the dome to fit the base/hearth that you built.

    As far as depth of the footing - I'll defer to more knowledgeable people.
    Everyone makes mistakes. The trick is to make mistakes when nobody is looking.

      Thank you!
      Now figures for the corner installation in the plan (on the page 15) look even more mysterious: I can't get a clue what 48" of external diameter can mean anyhow.
      It's look like a mistake.

      UPDATE. I've got a clue. That are figures from Prefabricated Refractory Pizza Ovens Installation Guide - and they are just not suitable for the brick dimensions.
      Thank you again!
