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!

Dome Installation Video - Casa / Premio / Modena

Hello,

For many of you who bought a modular oven, you may have asked how we put the domes together when we build them. For those of you considering one of our ovens, we shot a video to make your install easier.

Check it out on our You Tube Channel.

Thanks for participating in our Forum. We will have more video content available soon.

  • Fiberglass Insulation for Dome

    My oven dome is made from about 3-4" of clay/sand and 1-2" of perlite/cement. I would like to insulate it further by wrapping the oven in home fiberglass insulation but am worried that the heat will pass through the clay layer and through the perlite burning the fiberglass and that nasty binding. Do you think this should be a concern for my oven or is the 1-2" of perlite/cement enough to block out enough heat from the fiberglass? Also is 1-2" of perlite/cement enough insulation or do I need a second layer of some type of insulation? Thanks

    Re: Fiberglass Insulation for Dome

    I used fibreglass insulation for the first oven I built. It was a cast oven with2" thick walls. The insulation sat right against the walls so must have got pretty hot especially as the walls were so thin. On dismantling the oven there was no sign of deterioration of the fibreglass at all, but some people have reported that the binder burns. Maybe depends on the brand. I found the most difficult part was getting a good shape without the stuff compressing and therefore reducing its insulation value, but this would not apply if you are doing an enclosure rather than an igloo.
    If I were in your position I'd be just increasing the perlcrete layer to 4", but keep the mix lean (no more than 10:1) Even at 10:1 you've got more mass in cement than perlite and the cement only reduces the insulating capacity.
