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!

  • Casting a vent?

    I am thinking of casting my vent for my 42" oven. The instructions say to cast it using a form etc. They do not say if it needs to be a special type of refractory concrete or just regular concrete.

    Will regular concrete handle the heat in the vent/chimney?

    Cheers

    No: The vent area, particularly down near the oven, gets very hot. You need to cast it out of refractory, or build the transition up with firebrick.

      to add to dmun's comments - be sure to use a castable refractory, not Refmix, Heatstop, or the fireclay home brew mortars. I think various manufacturers also offer insulating castable refractory as well.
      Sorry for the lack of specifics, it has been 1 1/2 yrs since I actually researched this myself (opting to stick will brick, a Duravent transition plate and Duravent pipe for a chimney)

        A quick and easy solution to this problem is to cut your transition out of stainless steel and tack it together as I have just done for Hendo's oven (pic)
        I will arrange to fit it with the lights on Saturday with a few small dyna bolts located in the centre of the firebrick archways.
        It also makes the fitment and aiming of the oven illumination a breeeeze.
