New Forno Bravo Forum Feature

Forno Bravo Forum Community,

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.

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.

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!

  • Castable Refractory Insulation

    Hi Everyone,

    Today I came across a Harbison-Walker castable refractory insulation, Greenlite 45L. It comes in a 55lb bag is listed on eBay for around $38. The link to it's
    thermal characteristics is:

    GREENLITE-45-L PLUS 55# BAG - 10023

    I'm about to pour my foundation and support stands for a 42" Pompeii shortly and I wonder if anyone has used this kind of product to insulate under the oven floor?

    Cheers,

    John

    The linked site shows the product at 72 pounds per cubic foot, so you would need a lot of bags. You're going to need a bag for every two square feet if you're pouring a four inch layer. If it were me, and it was a cost-no-object situation, I'd go with the insulation boards. And, if you're mixing the stuff up anyway, why not use the proven vermiculite/perlite solution and save a bunch of cash?

      David,

      Looking at the numbers, you're absolutely correct: This stuff IS expensive. I'll go with the vermiculite. Thanks!
