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!

  • Insul Cast Delta Crete

    Howdy,
    Has anyone heard of or used "Insul Cast Delta Crete" ?? It is an insulating refractory castable that may also be troweled in place. As part of the description it says: Ideal for insulating solid masonry in bread and pizza ovens". It also states to apply a minimum of 2-3 inches thick over top of bread oven dome. Does this material sound like a useful insulator instead of a blanket wrap and vermiculite??? Or maybe in addition to?? It is made by the same folks who make Heat Stop 50.

    As a general rule the denser the material is then the poorer an insulator it is. I'll bet the stuff is a lot heavier than vermiculite or blanket, therefore you'll probably need a thicker layer.

      If it's priced like heat-stop, you may be driven back to vermiculite. Not saying anything against heat-stop, I've used it and like it, but boy is it expensive.

        All of the premixed refractory products are dear. We'd be better off making our ovens from mud. I was talking to an aboriginal guy the other day who told me that people up north tunnel a hole into the base of a large ants nest, many of which are as tall as a person and quite numerous. They then simply light a fire inside, throw in whatever they want to cook and seal up the hole with something.
