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!

  • Blanket Deteriorating in Rain

    Hi, I have been searching the FB forum for topics about how to deal with a soaked oven after a spell of rain with poor waterproofing. Lots of posters said that while it is a pain, a soaked oven can be rectified with a few steady fires. Is it the case that the insulation blankets can be soaked and dried out numerous times or will they deteriorate pretty quickly?

    I am going to use this Rockwool 159 blanket. This blanket resists temperatures up to 1200F and absorbs water at less than 1 kg/m (not sure if the water absorption rate is good or bad).

    Cheers,

    If your waterproofing is bad enough to let water in, it's got enough gaps to let water vapor out. Go with low and slow fires, and your insulation will dry.

    You might want to consider an enclosure to keep your oven dry enough so this doesn't happen.

      I'm confused. If you haven't put the blanket on yet, why are you worried about the affects of water? If you do a good job - it's a non issue. I would worry more about burning your food.

        The oven is outside and I'm not planning to put a roof over it. It doesn't rain much here in Andalusia but if the tarpaulin isn't on it by mistake the blanket may get wet as I have a rock exterior and only artlita/cement/lime protecting the blanket. If it gets wet every now and then and I just have to dry it out with a few steady fires it's not a great problem unless the Rockwool blanket will start deteriorating due to exposure to water. It says in the Spanish spec for the blanket that the blanket "doesn't retain water as the blanket doesn't have a capillary structure", so that sounds like it will help somewhat.

        Thanks for your time & patience, you lot are a real Godsend,
