What is this?

This was left in Textiles because it looks like quilt batting. It appears to be ceramic batting from look and feel. It left a power on my fingers when I touched it and it’s quite heavy for it’s size. Anyone know where it came from and what it truly is.

The bag is from a rock and masonry place if it is in the original bag…

I’ve gotten several of these bags from the Yard. I think I might have seen this batting there too. That’s another reason I’m guessing it’s creramic batting

It is Kaowool. It is a refractory ceramic material for lining a gas forge.


Thanks for letting me know. It’s currently setting in the hallway.

I need to buy some of that someday for my foundry project
