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!

  • Theremocouple,sand & fireclay?

    Not sure how much sand and fireclay I should shop for for the paste needed for seting the firebricks on the hearth for the oven floor.
    Also not sure how the thermocouples will work. I have not seen one or really know exactly how they work. What do they look like (Physically how big etc)? Do they sit below the firebrick floor or right inside the oven? How many do I need and what be be the idea location? Planning on pouring the foundation and the stand walls and the stuctural hearth all in one pour this Friday. It will be an exposed agragate round 70" diameter stucture with a ring on top 4" high to hold the insulating pour to follow. I will try to post a picture after the forms are completed hopefully tommorow or day after....thanks in advance for this Wayne Bergman Canada

    Re: Theremocouple,sand & fireclay?

    Hi Wayne,
    I know what it is like to over order. I purchased 5 x 25Kg bags of fireclay and used around 15Kg for the whole of my 40" Pompeii. That was used in the por man's mortar and for bedding the slightly narrower fire bricks into the heart, but I used it dry, not mixed with cement nor water.
    Hendo came and bought a bag but it is a bit too far to post one over to you.
    I have 4 thermocouples in my oven, on just under the cooking surface in the centre of the hearth, one on the underside of the hearth bricks, one around 15mm into the centre dome brick and the last measuring the temperature soak through the dome. There are different types but the K type that I used are made up of 2 different wire types which are fusion joined (welded) at their very tip. this joint of differing metals produce a very small electric current which is read on a sensitive meter and displayed in degrees Celcius or as the Americans use Fareheiht.
    See my link on:

    You won't need many, if any at all. I have more use for my Infra red thermometer that I aim into the oven for surface temp readings rather than the thermocouples. Once you get up and going, you will get to know your oven and temps and not use or rely on the thermocouple readings. The one thing that they do well, is to let you know how deep through the bricks, commonly known as 'soak', the temperature is so that you can establish how many cookings will be achievable at the time.

    Good luck with your pour.

        Hi Wayne,
        Forno Bravo have these infrared thermometers on line but as we don't have FB here in Australia, I purcheased mine from:

        http://www.maxtool.com/index/Digital...ermometers.asp

        I paid via Paypal anf the thermometer arrived within 6 days. Great sevice and a good product.
        Simply aim the laser pointer to where you want to read the remp, select the readout as °C or °F, press the trigger for 1 to 2 seconds and read the temperature. That easy and accurate to +or- 2°.The one I got is a MTPro and cost US$59.

        Do a Google search for 'Infrared thermometer' and find a supplier near you.

            Can you share with us a link to where you bought it? I'm starting to shop for one.

            Thanks!

                No problem.

                I am just sitting here bored as heck at work.

                Ughhhhh

                At least it's Friday~

                You might check out eBay, that Max tools website has the same gun but 10 bucks cheaper.

                Your dome is looking awesome. BTW
