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!

  • Isol insulation adhesive

    What is the point of gluing the isol board to the hearth? It seems to me that with all the weight, mortar and insulation that it won't move. For those that have used this product, did you use the adhesive?

    I put my insulation boards down on the wet concrete slab surface. Solid as a rock. My brick floor I laid loose on top of the insulation, and they creaked and groaned as I stood on them to build the oven, but they seem pretty solid now.

    You're right. It's like the riggers say: Gravity always wins.

      Re: Isol insulation adhesive

      I used a high temperature adhesive - Kaogrip - for two reasons - mainly to level my slab and give the Cal Sil sheets a 100% flat surface to sit on. Putting the sheets down on the slab without the glue there were many hollow sounding areas.

      The other reason was practical - I figured I'd probably bump the sheets and open up gaps when laying the floor etc, and the glue held them in position during this procedure.

        Ditto Hendo's concerns. Although I just used the plain old Heatstop mortar.
