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!

  • Oven diameters vs hearth

    Hi Guys.

    Im Building the 42" inch igloo version of the pompeii.

    Just have a quick question about the hearth im about to pour within one week.
    According to the Pompeii oven plans the oven exterior for a 42" inch oven should be 51" - but do i have to add the insulation of 6" on top ? and the insulation does that also covers stucco etc, which would then make the total 57 inch = the finished product in my case ?

    Im a bit affraid that I might have made the hearth to small. its a corner installation that's approx 61" by 61" ? (I dont have the possibility to make it any bigger)

    My final question, do i need to downsize to a 36" or what do you think ?

    You don't have to drop the diameter to 36" you can go 40" or 39" or what ever works for the size of hearth pad you have. I took my 42" igloo right to the edge of the pad. That said,

    42" ID, 9" (4.5" x2) brick, 6" (3"x2) Use CF blanket is you are need space vs Vcrete, 1" stucco =58". The hard part will be the vent landing.

      Allright, thank you.

      I will also use CF blanket. But think I will size down in order to have propper landing+vent area.
