I'm Peter Reinhart! Ask Me Anything! Monday, February 15, 2016 7:00-8:00 pm EST

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!

  • getting a smoother finish on vermicrete?

    Hello,

    I tried to post this yesterday but think maybe I did in the wrong part of the forum or somehow didn't submit it.

    Anyway, though I love Pizza and this is an amazing site for pizza ovens, we use vermicrete to make some outdoor pieces and have been stumbling with getting the finish on our products perfect.

    We have been casing small planter boxes out of this material using two grades of vermiculite one very fine, and one coarser that we buy from a garden store locally in 6 cu. foot bags.

    My question is if you look at the two pictures I attach, you will see I have a nice smooth finish on all aspects of my finished product that touch our melamine forms, what I get a chunky loose look on is the top of the product where the mold doesn't close over it.

    I think maybe this is due to not pre-soaking the vermiculite to be sure it doesn't absorb the water or skim layer that should give the final nice finish on top, but Im' not sure, so any advice or hints or tips would be appreciated.

    One pic attached shows what it should look like, other is what I get on the top of the product where you might trowel, but trowel or not, doesn't come out right for me.

    Thanks,

    Justin

    I find you can get a better finish with the finer grade.it is important that the correct amount of water be used in the mix. The finer grade will need more water than the coarse stuff. You could try making the top surface a little richer ( more cement) also try adding a little powdered clay to the mix. Both these things should make it trowel better. Also a 50/50 mix of vermiculite and perlite will make a more workable mix than either of them alone.
    Kindled with zeal and fired with passion.

      You may have to make a slurry and use a melamine trowel to finish the exposed portions as well.
