Groin vault base for a hearth. Is it possible? - Forno Bravo Forum: The Wood-Fired Oven Community



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!

  • Groin vault base for a hearth. Is it possible?

    I'm still in the early design phase of my oven and have looked at thousands of photos. It's just my aesthetic taste but I feel that many of the ovens I've seen appear squat and heavy. (I know, they really are heavy) so I was wondering if it would be possible to make it appear lighter by incorporating a groin vault, two intersecting barrel vaults, in the hearth. Essentially, it would appear to stand on four legs. A google search turns up nothing. Has anyone attempted this? Is it even possible on that scale or am I dreaming?
    I'm no mason, so I know the extreme difficulty of doing what I'm thinking but I'm just curious if it can be done. Would you do it in brick? what about pouring it in that shape? Any thoughts would be much appreciated.

    1. Yes, it's possible.
    2. No, I don't know how to build it. Gut reaction is that your vault will be pretty massive because the top of the vault could be upwards of five feet across.
    3. You could do it with brick. One of the largest domes in the world is nothing but brick. If you could make a form for it, you could just pour concrete with rebar.

    It's an interesting design idea. Good luck with it.
