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!
It will never be like plain cement. It will be sort of spongy- sort of like cork. It will also crumble around the edges if you mess with it- I know it seems as though it will never be suitable, but it does work. I have several inches of it under my dome, and it's never compressed at all- but it was a major leap of faith to go ahead and trust it!
I decided to minimize the amoutn of space covered to 2" beyond the hearth foot print and am using a round form to create the round shape---I am thinking that I never want to remove it for fear over time this 5:1 mix may crumble..to dust. PS my vermiculite is not the 3/8in size but the 1/4 to 1/8 size.....see any problem permanently leaving the frame or the 1/4 size verm.?
What about the really fine perlite, about the consistency of laundry detergent? I posted a question about it this morning but haven't received any responses (my post's verbosity may have scared off potential readers/repliers). Is that too fine to make good insulation? I already wrote this in the other thread but my concern is that it will pack too tightly and won't leave any voids for air...which is the critical function of any insulation of course. Would the answer differ depending on loose-fill vs. permcrete or do you want the same grain size (whatever "right grain size" means, large or small) regardless of whether you are loose-filling or making 'crete?
i need some info on heat bond refractory mortar. does it mix with portland cement and set well for building a pompeii oven? i use air bond mortar now but i was told it will crack easily. please advise.
To answer two posts in one shot Neil2 is right, wait about a week. Even though everything my eyes told me the perlite and portland mixture was wrong after a week is was hard enough to stand on whilst I laid the bricks. Yes the edges to flak off at the corners but once I put brick around the base and skimmed mortar atop the perlite it was all fine. And Neil@ is right about grain size, I bought the detergent looking stuff and ended up giving it away. Here in Austin I went to a Hydroponics store and got the coarseness that I really needed at a good price. With shipping charges alot of the mail order stuff is, how do they say it? Too dear.
