Help - attaching Arch to Oven - Forno Bravo Forum: The Wood-Fired Oven Community



New Forno Bravo Forum Feature

Forno Bravo Forum Community,

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.

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.

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!

  • Help - attaching Arch to Oven

    I have a modular oven that came with a preformed arch made out of what lloks like clay. I tried attaching the arch to the oven using te refrax but that did not hold and I have also tried the motar i am using to build my brick surround but that did not stick either.
    does anyone have suggestions on what o use to attach the arch to the front of the oven?

    Hey Mike,

    Try using a wood form/support/brace (a couple of 2"x4"s at an angle) to hold the arch in place while the mortar between the arch and the oven chamber sets. I would put a 3/8" strip between the arch and oven, then pack a good 1"x3" band around that joint.

    That said, the mortar shouldn't have to "hold" the two together. The arch (I have a mental picture of oven you have) should stand freely and tightly next to the oven. The mortar really is just sealing the two together.

    Let me know if that works. Of course this wouldn't happen with a Forno Bravo oven. Just joking.

        soak it?

        With the brickwork I did I found there was some difficulty forming a bond until I learned (I think here) to soak the bricks first. Mortar cures best (like concrete) when it stays wet for a while (although wet mixed mortar is not as strong as a relatively dry mix), plus a too dry mortar joint has no "grip". The trick I think is to have a mortar you can spread like thick frosting (describing the consistency, others say like peanut butter) and let the masonry you are bonding provide water supply for the curing. Perhaps you can briefly soak the two pieces, or if that's impractical wet them with a brush or a wet rag. Really douse them if you are unable to soak them. If you do drown them first keep them under water until they stop hissing.

        Good luck!

          Good idea

          That will also help. A dry refractory will suck the moisture out of your mortar, and it won't cure properly. You can end up with hairline fractures and even cracks that let out hot air and smoke.
          Thanks for that.

            Refractory Mortar


            You are exactly correct about wetting the bricks when using refractory mortar. For those who are familiar with laying ordinary brick, the water will be sucked out of refractory mortar and fire bricks about three times as fast as with Type S mortar and ordinary bricks: common, fancy facade, what have you.

            If you can't soak the bricks, as with standing bricks being added to, one at a time, brush the brick already in position with lots of water, then soak the brick to be applied until it stops hissing.

            Lay three bricks, then point the joints to seal. This is much, much sooner than with ordinary mortar and bricks. Carve off squeeze-out at about the same rate; otherwise you'll be hunting for the cold chisel and hammer.
