covering the dome - 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!

  • covering the dome

    Do I have to cover outside of dome with refractory cement or is that just to put dome joints together. Can I fill in and smooth out the outside of dome with portland cement . Do you have to use both the ceramic blanket and portland cement@vermiculite for insulation or can you use just use portland cement @ vermiculite for isulation on outside of dome. Then Put stucco over that

    Re: covering the dome

    There's no reason to cover the dome with cement. Some people do this to add additional thermal mass, but there's no structural reason for it.

    You can insulate with the blanket, or with vermiculite concrete, or both. The blanket is twice as efficient as the vermiculite concrete, so you need less thickness if you use it. The blanket doesn't cover the dome very evenly, it's lumpy with the overlaps and wrinkles, so folks who want to finish in an igloo shape sometimes cover their blanket with the vermiculite mix to get a smooth base for the dome stucco.

    If you use just the vermiculite concrete, you are going to want at least a four inch covering, maybe more at the top.
