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!

        I've seen a couple threads discussing use of the S or N type cement but don't know how to find them on short notice...

        If you want refractory home brew per per the pompeii oven plans, you'll need to use ciment fondu (calcium aluminate) instead of portland. I believe experts here have posted portland as one ingredient in S & N type bags. I'm using ciment fondu and home brew recipe because of James' report that the mixutre heats faster and holds heat better than the home brew with portland in it. HTH

        This thread & this thread discuss what you are after, read down quite a ways.

        This may be your answer....?

        If you are thinking about building a brick oven, my advice is Here.

        I try to learn from my mistakes, and from yours when you give me a heads up.
