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!

  • Yet another curing question

    Ok, so my dome had been completed about 1 month ago and had been drying it with light bulbs in it.
    I cemented the flue yesterday and will be encasing it with bricks.
    The question is should I wait 1 week after I am done with any cementing around the flue before using charcoal or it is ok to start with charcoal in the dome while I still work around the flue?

    Yannik,

    Much of the heat inside the dome will be exhausting through the flu you know causing the flu to get hot. If the cementing around the flu had some moisture it is likely to crack. I would go with waiting all the cement (even around the flu) to dry well before starting to cure.
    Why is this thus? What is the reason for this thusness?
    I forgot who said that.

      How long would you air dry things before the first small fire?

        The small amount of mortar you used to set the flue doesn't need a week to cure. Also, it's going to crack (a certainty) no matter how long you wait, because the dome is going to expand differently than the flue.

        Fire away and keep building.

          Another way to help legitimize a heatbreak,................is to think of it as an expansion joint .

            In certain places it's not optional like a break between the vent and oven opening......like when the flue comes through the crown of the chimney.

                Well, I guess everything is optional. What I mean is, not optional if you don't want a cracked flue (clay)...not stainless.

                  Not quite I separated my vent flute from the dome with heat break and insulation even though I wrapped it around the dome entry arch. Substantial difference in temperature still bloody got though.

                    It is optional in that with or without a break, the masonry isn't subjected to damaging expansion. Stopping heat from migrating into the vent masonry is optional, is not detrimental, and the performance gains are minimal.

                      But, will improve "greatly" after all is dry .
