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!

  • Is she insulated ok?!

    hi all

    i have recently completed building my first wood fired oven (casa 2g 100), and am ridiculously excited...

    built an igloo style, with the usual 3 layers of blanket, followed by a vermiculite / concrete / sand mix, chicken wire, and then outer layer of render. looks awesome.

    my only slight concerns...

    a) the bit of left over mortar that came with the kit, used on outside of the dome joints, did not 'go off' and felt a bit crumbly... is this usual?

    b) am now into the curing process, and last night was fire 3 - around 300F with kindling and small log. temp probably got up to 400F at one point on the top of the dome, and the outside at the top felt slightly warmer to touch than the rest of the dome - 75F ish (with my infrared thermometer!!) as opposed to 60F elsewhere.

    is this usual and i am being paranoid, or do i have insulation issues?!

    all thoughts welcome.

    cheers

    "is this usual "

    Yes. Initial firings will generate some steam, this can sometimes be seen coming out near the top.

      thanks neil

      so as i continue the curing process should it cease to be warm on the outside?

      cheers

        Re: Is she insulated ok?!

        apologies, another quick query...

        i have noticed that the cooking surface slabs have separated slightly. are there any issues with pushing them tight in the middle and filling the gaps at the edges with fireplace caulk?

        many thanks indeed.

          They will happily fill with wood ash. I wouldn't use any mystery compounds on your cooking floor.

            "any issues with pushing them tight in the middle "

            Agree with the post above. These hearth bricks will always move around a bit because of the teat temperature range they go thru. Adding additional caulking may actually be detrimental.

              Sounds like everything is going fine. Continue the curing process and the oven will get better as the the water escapes from the oven. It takes a number of fires to drive all water out. Even after the oven is cured, the oven will continue to improve it's heat retention properties.

                  You are on the road to pizza, Jon. Just be patient a little longer...And start using your residual heat to cook with - a roast, a stew, something you can put in covered and leave a while.

                  You will be there soon!
