Oven door questions - 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!

  • Oven door questions

    We finished the perlcrete layer thanks to all your help- I'm using a space heater for the next month at night just in case.

    I'm experimenting with the materials I have left over to make a door, and wanted your input, if possible.

    I have a piece of 2 1/2 inch thick foamglass covered with hardware cloth, with reinforcing sheet metal on both aides, and wooden handles held together with carriage bolts- please don't laugh at my amateur attempt at door design.

    I made a wooden form and am planning on casting the door using a mixture of perlite and refractory cement (4 to 1) to surround the foamglass/hardware cloth, then sealing the casting with a thin layer of the refractory.

    Does this seem like a crazy idea? At least I will get experience with casting which interests me.

    Thanks in advance.

    i've been down this road too, I think you will find 4:1 too weak. If it were mine I'd use 3:1 or 2:1 What you gain in insulation value you lose in strength. Perlite can be fired up to 1100 C by the way. You can increase the strength by firing the panel, but you probably need to go to 1000 C. Ask your local potter.

      That will double as a great fish grill.

        Have you thought about using metal plate over the mesh? Masonry materials don't seem like a great coating for something you need to slide in and out of an oven. Too brittle.
