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.

If the link doesn't work, simply go to You Tube and type Forno Bravo Channel. The video title is How to Set your Forno Bravo Oven Dome Pieces.

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

  • Heavy density fibreglass slab - suitable?

    Dear All,

    I have (possibly wrongly) worked out that the temperature under the fibreboard insulation slab will be around 50C, which I think indicates high losses.

    So I bought some inexpensive high density fiberglass slabs (Wickes in the UK sell them) to put under the FB.

    The slabs are fibreglass, designed to go into cavity walls or under flooring, quite dense, about 2in thick and would surely bring the 50C down to not much at all. And they would not be exposed to high temperatures, as these will be taken off by the FB. That was my rationale.

    On the specs for the fibreglass slab printed on the packaging there is a sub-flooring application (under concrete screed), so I hope that it will remain stable under the relatively small pressure from the oven, spread over the approx. 2sq.m. of oven support area.

    So it will survive (even if it will compress a bit). But will it be mechanically stable? I would not like a wobbly oven, to put it bluntly.

    So here is the question: has anybody here had experience with this type of material under the oven? And if not - any advice/suggestions/warnings would be also much appreciated.

    Many thanks in advance,

    W.

    You'll surely get a better informed reply, but I think most insulation board products include compressive strength as part of their product specifications. I've usually seen this given in pounds per square inch. For example, some Dow Styrofoam products are rated at 15psi, or just over 2000 pounds per square foot.

    I'd suggest checking the manufacturer's web site.

      high density fiberglass slabs
      if you call it so it is for shure they are of high density! Or you are not sure!
      Cheap doesn't mean better! Believ me!
