TESTEMONAIL:  Right and Discordianism allows room for personal interpretation. You have your theories and I have mine. Unlike Christianity, Discordia allows room for ideas and opinions, and mine is well-informed and based on ancient philosophy and theology, so, my neo-Discordian friends, open your minds to my interpretation and I will open my mind to yours. That's fair enough, right? Just claiming to be discordian should mean that your mind is open and willing to learn and share ideas. You guys are fucking bashing me and your laughing at my theologies and my friends know what's up and are laughing at you and honestly this is my last shot at putting a label on my belief structure and your making me lose all hope of ever finding a ideological group I can relate to because you don't even know what the fuck I'm talking about and everything I have said is based on the founding principals of real Discordianism. Expand your mind.

So the pictures i've seen of this material always shows blocks of it.
If it relies on some special drying technique, then i'm guessing that its formed at manufacturing into a rigid structure?  So you couldn't blow it in like conventional insulation....
i guess it would be used in insulated structural panels?

Wouldn't be unthinkable just to use panels.

the article says its being sold in sheets.

The melting point is 1200 C, I can't find an operating temperature (the point at which the material degrades).

However, its apparently transparent to certain IR frequencies, that peak around 300-600C, so some high temp stuff might have a problem with it.  There's some work being done on making variants that don't have that problem, but they have issues.

Edit: The paper I'm getting this from is ten years old, so the issues with the variants might have been fixed.

It would be ideal for glass kilns which only need to go to 815c. Ceramics have to go a bit higher, but it would probably still be workable. I mean, firebrick degrades over time anyway, why not use a massively more efficient material?

Oh, you probably know this Nigel, what's the operating temperature of firebrick?

*has been searching for a workable very high temp material for a mad science project.

Never mind, I found it, it would melt  :argh!:
