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!

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.

  • Recommended insulating concrete ratio?

    I believe (I don't have it in front of me right now) that the Pompeii directions suggest a 1:5 ratio (portland to vermiculite/perlite of course). On the forum I know I have read mention of some other ratios, at least at divergent from Pompeii as 1:7. I don't recall specifically.

    What is your recommended ratio and why?

    Followup: Do you believe the ratio should be varied with vermiculite/perlite "grade", which refers to the size of the grains? That is, would larger or smaller grains require an alteration to the cement ratio?

    Standard grades, as I understand it, are in four steps (generally labeled 1 to 4, 1 being the smaller grains), the smallest being sand-sized, the largest being dime-sized, the two intermediate sizes being, I dunno, BBs and half-dimes respectively, I suppose. What "grade" did you use and what are your thoughts on it?

    Re: Recommended insulating concrete ratio?

    For the vermicrete insulation under the slab use 5:1 for strength. For vermicrete on the sides and top of the dome (for igloo style) use 10:1 because this layer does not need to be strong, but just enough to hold it in place. Remember that the more cement you use, the more you reduce the insulation value.
