    I got the 25.
    I have plenty of air, so no problem.
    I figured I could always run it slower.
    If your going to cross over to the dark side, GO BIG !

    I will ask them after it is all over, but I am not sure they will tell me.

    I thought about that, but I am under the "pressure" at work, so no time for fun stuff.

    This video pretty sums up my work load right now:

    So Pat, I believe Plastic A is a Plibrico product. Is that correct? What is this second 3800F rated plastic? Have a name, manufacturer, and/or data sheet for it?

    Best,

    Yes, in some cases that is also true.

    I think it is a custom blend, apparently made locally.

    Here are photos of the furnace after the patching and one iron pour.

    If the results after one iron pour are any indication of how the Plastic A material holds up to iron temperatures, then I think I have stumbled onto something very good.
    The Plastic A is absolutely as hard as tool steel.
    I though I would scrap/scratch/chip a bit off it off just to see if I could, but you can forget that.
    I finally found one tiny piece of aggregate protruding out that I was able to break, but the stuff is more solid than the Mizzou, and I don't see any signs of it scaling or breaking away from the hot face.

    Most impressive stuff, and I just slapped it on, and fired it immediately while it was still wet.
    For a furnace hot face that was broken into four pieces, it basically works now like it was new.

    The 1" thick ceramic blanket on top of the domed Mizzou looks good.
