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.

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!

  • Insulation blanket rating needed.

    Can anyone advise what rating of insulation blanket is need for a wood fired pizza/bread oven. Is a rating of up to 450C/850F sufficient or is a higher rating needed. Also what is the best way (other than to build a roof over the oven), to avoid the blanket becoming wet. Is there some particulat type of waterproofing paint that can be used.

    Blanket normally is rated to 1200 degrees celcius.. normally made containing alumina silicate. where in aussie are you?

    once blanket is on.. you normally stucco render the whole oven.. look at some builds on the forum and you see examples..

      Thanks for the reply. The reason I mentioned insulation rated to 450C was because I was told the inside temerature of the oven would not usually exceed 450-500C and that cooking above this temperature is not really viable.
      Are you suggesting that the higher rated 1200C blanket will work to help to store the heat in the arch bricks for a longer period of time?

      By the way, I'm in Newcastle.

        Normal pizza cooking temps are 750F.. sometimes a little higher, sometimes a little lower. You should go with the higher rated stuff. It might not work any better than the other stuff, but it's not going to catch fire.. that's the main concern. Whoever told you that the oven wouldn't get hotter than 500C? Easily doable in my opinion.
        My oven (for now):

          500C is what, 932F? That may exceed any workable cooking temp, but remember, you will be building big fires which easily exceed 500C. The hottest I ever recorded was over 1400F (I won't do that again). Typically, the center of my dome reaches around 1150F while clearing.
          I would go with the higher rated blanket.

            Agreed with above. The last thing you want is to exceed
            The temps the blanket can take.

            Ring around pottery shops? Not that expensive
            Mate. $70 for 3.6 meters at 600 wide.

              Thanks for all the feedback guy's. Thats great advice. I had no idea the a lower rated blanket could actually catch fire is the temperature exceeds its rating by too much.
              I will definitely go for a minimum of 1200F.
