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.

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!

  • pre soak vermiculite for a smoother finish?

    Hello Folks,

    We are working on some little architectural pieces, not an oven, though I've found all kinds of info on your website and appreciate it being out there.

    We are using a mix of vermiculite sizes one larger grain from a garden center that comes in 6 cu. foot bags and the small tiny grains from Uline, the shipping folks, great to work with.

    We are trying to get a nice cosmetic finish in our molds and we are for the most part. The parts that are surrounded by the mold come out nice and smooth as seen in the second picture. However the top of our mold where it is exposed and could be trowel finished, etc... seems to always come out rough.

    I'm hoping someone with more vermiculite experience can provide some guidance. I've heard some people soak theirs overnight while others mix and go.

    We haven't soaked overnight, but before I waste more product and get the same rough result, I'm looking for any sage wisdom.

    It makes sense to me that not soaking overnight on this absorbent aggregate might be causing it to suck up the layer of milk or water that forms at the top and therefore we get the ugly finish pictured second below.

    Any thoughts greatly appreciated, sorry not oven related, but hope you'll help me anyway!
