Oven Chemistry - Forno Bravo Forum: The Wood-Fired Oven Community



I'm Peter Reinhart! Ask Me Anything! Monday, February 15, 2016 7:00-8:00 pm EST

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.

Ask Me Anything New Forum Feature

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.

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!

    As I fumble through this curing process I have read many threads that talk about the stages the oven goes through but I am curious about the 'bricks turning white' bit?

    What is happening to the bricks to make them turn white? On my 3rd curing day the entire inside of my dome has gone black from the smoke I guess (note I have used old red bricks), should i expect these to eventually turn white with continued firing?

    Surely continued smoke = continued black? Or is it something to do with moisture?

    Going white, or more commonly "clearing the oven" is when the temperature is hot enough to burn off the smoke, soot and tar. The black you currently see will go away and the brick will be clean. Just like a self cleaning oven. It works the same way.

      If you pay attention, you can actually smell the soot burning off the bricks, the smoke will take on a slightly darker grey and you will smell the plume (not a nice smell at all). It will last a few minutes (more if you have been doing a lot of smoking and have built up a lot of soot/tar on the bricks - like I do). A raging fire doesn't produce a lot of smoke, but when the dome begins to clear, you can smell it.

        Your oven will turn red.

          When the black soot burns away you are left with the colour of your bricks. If they're white then the oven dome will turn white. If the bricks are red then the oven dome will turn red. The intensity of the flame will make any colour brighter and paler.

            And the next time you fire it , it's soots up and the process starts again.
            Fire is in all of us, flashing up a cold oven , 2 hours later you can still have a 9 yr old attention .... Completely. You figure out perhaps its in our makeup
