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!

    Cant remember what it was that we dont want in the perlite. Some grades come with something added and I cant remember what that was. Was it silicone? My product is called ZONELITE PERLITE it is sold by Grace Perlite and has the INDUSTRIAL grading on it. Does this sound ok to use. I had Vermiculite for the hearth and all went well but now I have perlite for the Dome cover later on....thanks wayne

    zonolite is vermiculite that has been treated so as not to absorb water...designed for insulation concrete block walls...insulating properties still ok but will not work to make the insulating lightweight concrete because it will not mix with the water and cement..
    Can't wait for the next one!

      Re: perlite content

      Thanks for the help. Guess I will return it to the lumber yard. It amazes me how sales people that work in this brick and mortor industry have no clue as to what we really need to get our project succesfully done. Do you know if this product will be ok in the garden....if so it will save me trip back to the store for now and will pick up some vermiculite later on for the dome outer insulation...thanks again Wayne

        Wayne, if your building an enclosure over your dome the Zonolite should be OK as loose fill insulation. The treated stuff (I believe you are correct - silicone) doesn't bond with portland cement (so I have read).
        The silicone acts as a lubricant, allowing it to slide into voids more easily and repels adhesion.

          Re: perlite content

          Thanks rt, but no I am not doing an enclosure. Sounds like I got the wrong stuff. Glad you folks are able to set me straight. This purchase was on back order for some time so I ended up buying the vermiculite for the hearth while I was waiting for it to arrive. Good thing I got the right stuff for the hearth. If I understand things right I might be better for people to just stick with the vermiculite as I think all vermiculite brands are the same unless you know what you are doing and able to read between the lines on the perlite differences. I specificly told the sales guy what I was doing also and had it shipped here on a ferry and the whole deal. A bit of a pain. The problem for me here in Canada is the shipping cost from the states for all of these bulky or heavy products so then trying to get something similar like high heat mortor etc here in Canada and sales guys are not knowing there stuff or dont care eneough.....wayne

            Not just in Canada. When I built my oven down here guys at the brickyards looked at me like I had a third eye when I asked about high heat mortars and differences in vermiculite. Shipping isn't so bad for me though...tariffs get you too I am sure!
