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!

  • Castaic FireBrick? Is it ok?

    Im using the same post so as not to muddy the site. I was curious if anyone had used this brick and was satisfied with it. I was unable to get an answer on the silica and aluminum content percentage.
    I bought some fire brick locally (Tucson) and it is the correct size 2.5x4.5x9, But it is red. So I wasnt sure if this is the right stuff. So i called the company castaic brick or pacific clay products. I inquired what grade it was, but they dont make different grades. They said its firebrick and will work for my oven. I had them email an msds sheet and here is what it says.
    Products Components
    <P> ------------------- CAS - % by Wt - ACGIH TIV - CSHA PEL
    <P>1. Aluminum Silicates: Var, 50-70, 10 mg/m, 15 mg/m
    <P>2. Mineral Compounds of Var, 7-9, 10-15 mg/m, 10 mg/m
    <P> Iron, Calcium
    <P> Magnesium:

    So I am confused as too what the actuall alumina content is.

    So if any one can comment on it, i would appreciate it. maybe someone has used castaic or knows something about it. I want to be sure, because there is no turning back once I start. Thanks

    I don't know about this specific product, but there is red firebrick. Well, sort of red. And it tends to fade.

      It should be fine. I have both red and buff firebrick and the specs are the same for both.

        I just dont want it to end up being insulating fire brick that wont hold the heat.

          As a rule, insulating fire brick will be white and light.
