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!

    Picture attached shows the make up of a castable I am wanting to use for a cast oven build. Molds are getting close to completion now for the casting of this oven.

    If the picture is too small this is the link to the tech info Technical Specification Datasheet Level 3


    I am also wondering about heat up times for a castable oven made with this product. The tech help from Cercast HT says they would not recomend a 1 hr heat up time on this or any of there castable products if it was only 2 inches thick. They say if going up to 800 degrees in that quick of a heat up time is way to fast and may crack it even if it was cured properly. What are peoples feelings on castables cracking easier than regular fire brick builds? Are all castable units pretty much the same for make up on the mortar? Maybe the tech help was just being over cautious and saying it needs at least a 2 hour heat up each cooking session to help the oven not to crack.

    You are correct about heat up times. The industry standard is 100 C/hr. at a rate of around 400 C/hr you can expect hairline cracking. But these hairline cracks never seem to get any worse. Any large cast pieces are subject to minor cracking, it is better to cast in a number of pieces so you can design where the cracks will be. The temp difference and resulting uneven expansion is the culprit.
