Use just heat stop 50 for shell construction - 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!

  • Use just heat stop 50 for shell construction

    Hello I'm new to the forum but I've been here looking for a few years finally gonna start the build, I'm a concrete floor guy so I'm not worried about the stand so much as the oven construction it's self I want to build the forms and then use the heat stop 50 over this ? First question is
    Do I mix he heats top 50 with anything other than water ( rock , sand, fiber etc)
    Second question
    How think do I make the walls and do I cover the form in sections or do I install the refractory in one go?

    Are you planning to use the Heatstop 50 as a castable refractory? It's intended for thin bonds between firebricks, not as a bulk refractory. It's also more expensive than a true castable refractory. It might work if you used crushed firebrick as aggregate, and the usual stainless needles for reinforcement, but it's probably not the best way to go.

      Go to a refractory supplier, tell them what you are doing and make sure you get a dense castable refractory not an insulating one.

        I went to the local supplier here in town asked about the crushed fire brick to use as aggregate they don't make the fire brick so that was a no go so at $1.48 per brick and $44.50 per 50lbs of heat stop 50 II IM going the fire brick route

          I was going to say that heatstop sounded like an expensive way to go, but I see you already figured that out!

          Do some research on home-brew for your mortar. It will save you some more money
