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 problem

    I just recently insulated my oven after curing it, and was excited to see how it would hold heat, so i decided to try cooking in it yesterday. About an hour after ignition i noticed that there was smoke coming off the top of the insulation. I know that I already had a couple cracks in the dome, but it was nothing major, i sealed them up anyway with more heatstop before i put the insulation on anyway. Any way, upon further inspection i noticed that it was not smoke that was wafting up but steam. i touched the blanket to make sure, and my hand came away slightly damp. I was just wondering if this is normal. It did rain last week after i wrapped my oven, and it is possible that the tarp i used to cover it leaked water. Does having wet insulation neutralize its heat holding ability?

    The thing that worried me was that even after 3 layers of insulation, the outside of the insulation mesured 133 degrees in some spots. I do not know whether the fact that my oven MAY have been wet was the cause. I was under the inpression that it would feel cool to the touch.

    I was able to cook a pretty fantastic pizza last night by the way, but i didn't notice that big of a difference in heat holding ability. After the fire died out, the oven went cold pretty quickly. I made sure that there were at least 3 inches of blanket around the whole dome, and four inches under the floor. The only reason i can see for my loss of heat is that i don't have a door yet. Is having a door imperative to maintaining heat for days like i heard is possible?

    lol, sorry for the long winded questions, i just want to make sure that my oven will work properly.

    "I was just wondering if this is normal."

    Perfectly normal. There is a lot of moisture in a new oven. Take your time curing it .

      Normal, for sure, and the rain likely got into the insulation - no worries.

      But...a door in mandatory for retaining the heat that we all talk about. An insulated door is even better.

      Congrads on finishig your oven.

        Thanks for the replies. I was really worried that the rain would mess up the insulation and i would have to buy more, but when I came home from work yesterday night, the bricks were still hot even though the oven wasn't at any sort of a cooking temp. So it has to be working to keep the heat in the bricks at least.

        Dusty, how did you build your door. I was thinking of using FB board to keep the heat in, i just don't know what i would encase it in so that it wouldnt just be a loose piece insulation.
        by the way, do you have any pics of your oven up? it would be cool to see another sacramento builders oven

          I used fb board to insulate my door. Basically, I encased the board in metal and put a handle on it. I will try to post a picture of it but believe me, it is nothing fancy. Works great though.

          I posted pics of my build as I built it, but I never got a photo page-thing together. I think most of my pics are on my thread "dusty dome is 4" tall", but if you really want to see it, come by the house!
