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!

  • best method for perlite insulation on dome

    what is the best way to finish off a dome that has 3-6" of ceramic fibre blanket insulation. I want to use 1-2" perlcrete and then a skim of external plaster/stucco and already have the fibre blanket held on place with a well secured chicken wire mesh that is streched tightly across the dome.

    From the FB instructions I can see that a second mesh layer is created and the perlite mix is pushed through this. Is this absolutely necesary, or will it be easy to apply the perlite mix onto the blanket?

    Hi Brad,
    you certainly have a heap of insulation!.
    I only put on a 1" super wool blanket and then 3 x 1" layers of vermiculite cement, See:

    I put over the blanket, some chicken wire and then managed to lather it all with vermiculite cement. This is quite difficult to work and I added a little fireclay to make it stickier. I started at the very top and worked my way down and around ensuring that I always trowelled the mix in an upwards direction. You will find it out when you try out. I have given all my experiences and tips in my build postings.

      It is easier to apply the mixture from the bottom up, so you have something for it to sit on. The more cement,lime or fireclay that you use, the more you will reduce its insulating value. A 10:1 vermiculite/cement is sufficient to hold the mix in place and it will set up quite firm so you can stucco over it easily.
