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.

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!

  • A Real Newbie question

    Hi all,

    I'm about to mix and pour the the 3 1/2 inch concrete hearth, per the Pompei oven PDF. But before I do, I want to be quite sure that I'm using the right concrete.

    I plan on using Sakrete High Strength Concrete mix, which is a mix of gravel, sand and portland cement, I assume in a 3 -2-1 ratio.

    Am I missing the boat here? Should I be using just sand and cement?

    Please advise...

    You do NOT want just sand and cement.
    High Strength Concrete mix sounds like the right product.
    I wouldn't recommend fast setting concrete.

    Have you already built the stand? Or is this pour the foundation under a stand? What reinforcement are you using? What did you do for drainage? (I assume that'll be a potential problem in FL)

    Some advice: Start a build thread. Post lots of pictures.

      yes, you want high strength concrete mix. 3 1/2 inches is reasonably thin. High strength concrete is used for counter-tops and is especially important to use if you have any parts of the heath that extend out and are not directly supported underneath.

        Thanks for the responses.

        I thought Sakrete was the right product, but I wanted to be sure, before I lugged 18 more bags of concrete from the Depot.

        As I noted, this slab will be for the hearth. The slab for the base has already been poured and the blocks stacked, filled and bond coated. once I get the hearth poured, I will finally be able to start the fun stuff.

        I'll start to post pictures as soon as I have something that is recognizable as the beginnings of pizza oven.

        Thx and regards

          You are probably on track and doing it but if not, make sure and use rebar. There is a lot of weight on the hearth slab. More weight than people realize.

          I often cook with wine, sometimes I even add it to the food...

            Hi Novaslo

            Listen to all the above and I will add once the base is layed, troweled and now going off if it is extremely hot I would, like I did put some wet towels over it and keep them wet. I did this for a fortnight so it goes off slowly. But it was 40C when I layed mine for about a month [or at least it seemed like that]. Haven't got one crack not even a hairline one but then again mine is over 12inch thick [due to position more than anything].

            Cheers Colin
