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 fast

    My dome is done and i have it wrapped with foil, i have the chicken wire but i cannot find any vermiculite or perlite in this country at all, I have gone to every plant nursery building store everywhere and nothing, not to mention i asked if there were any fire proof or temp resistant insulation materials i could use and still nothing. Does anyone one know any materials that I can use for insulation in the dome? I have all the components except the insulation and the blanket and vermiculite seem to be out of my reach here in Santiago. Can anyone give me an idea fast. I don't want to lose all my heat every time i fire the oven.

    If you are really stuck and the oven is under cover, would mud and straw work?

      Is cinder blocks a common building material in the Dominican? If so, check out some building suppply stores that sell blocks and bulding materials. At one time vermiculite used to be used to fill the cores of the blocks as the walls were built to provide some insulation properties.

      You might have some luck there.

        I assume that if you can't get insulation, you didn't insulate under the oven floor, so you may have a problem even if you can get vermiculite or refractory insulation at this point.

        Is Hispanola volcanic? There may be tufa or other lightweight rock that would work. I'm thinking that coral might do the same kind of thing.

        The DR has a huge tourism industry, hence a lot of swimming pools. Perlite or vermiculite concrete is commonly used to construct swimming pools. You might try pool suppliers.

          I got some of my first perlite from pool guys.

          For what it's worth, it had portland cement mixed in with it.

            Re: Insulation question fast

            My pool guys had both with and without portland cement and offered me the choice. I didn't know the ratio they had going of portland to vermiculite, so I just went with plain.

              Hi, I'm a newbie on this forum, but I was having a similar problem to Mark's. Brick ovens are extremely popular here in rural Mexico, but no one uses vermiculite. I don't even know how to say it in Spanish! I've hunted all over for reasonable alternatives and found nothing here that will work.

              Anyway, the tried and true insulation for generations of brick ovens here: a mixture of 1 part tierra muerta and 1 part caca de vaca. Yes, that's one part good, ol' dirt and 1 part dried cow patties. When in Rome, right???

              I'm pretty sure you've already solved your delimma, but maybe this could be useful for another oven-builder in a country with no Home Depot.

              Hope that's somewhat helpful!

                I love the last post. I have no doubt that it will work if nothing else is available. I think if you search ebay for ceramic blankets, you should be able to find the firm in Portland Oregon that (I assume) can ship you the insulation best suited to your needs.

                  Also look for Argilite...it's an expanded clay ball used in masonry insulation.

                  That's where I'd go, to a mason to see what they use for insulation from heat or the sun.

                  Good luck
