Has anyone experimented with this sort of DIY carbon foam insulator for furnaces? The video shows it working for forges and a small-scale aluminum melt.
I'm doubtful it would work well, at the very least, you'd have to make sure you run your burner on the rich side, a lean flame would burn through the carbon foam in no time.
Indeed, it would burn up, unless you coat the inside with Satanite or Fermit. But I don't see the advantage of C foam over kaowool.
It's pretty obvious that it won't last if exposed to open flame, but it might work OK if coated or otherwise protected from direct flame and air. I know some people at www.sciencemadness.org experimented with it a while ago...
The Mizzou hotface to wonderbread's Kaowool insulation should obviously be a thin layer of dense, flux resistant, 3200F Christmas Fruitcake. The stuff is nigh indestructible! Jeff
