New Forno Bravo Forum Feature

Forno Bravo Forum Community,

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.

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.

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!

  • Sawdust Clayslip Insulator

    I am building a cob oven crafted from Kiko Denzer's book and I am up to the insulation stage. I picked up a massive bag of sawdust free from my local woodworking shop and I was wondering if anyone had any luck with insulating with a sawdust clay slip and what their ratio of clay:water:sawdust. Thanks!

    I used about 50:50 clay:sawdust/woodshavings (by bucket full, not by weight ;-) )
    I dug the clay from the garden and it was pretty sandy already so didn't add any sand.
    first batch we made a very runny clay and then added dry sawdust/shavings gradually, but found it hard work. Subsequent batches we damped the sawdust first then and made the clay less wet.... this mixed in much more easily....
    Only finished earlier today, so I'll be leavng it for a week to dry before we know how it works...
