lots of uses, good up to 1300^oc

Best stuff ever in my opinion. A bit pricey locally at $1 per square foot, but unbelievably useful in my "little" foundry.

 

[necromancer]

they also have other products up to 1600^oc

it will pay for itself over time

No doubt about that. Already had a little runaway with my foundry, good old cuiosity... I will say that I incinerated high temp enamel
off the outside of the metal, through 2 inches of ceramic and 3/4 inch of refractory.... Lol.

That ebay link looks like I need to start buying rolls and parting them out. Cost me $100 for a 100 square foot roll locally.

Try looking up refractory on a local search and see what comes up. I was lucky enough to find a company that does industrial furnaces and sells material to the public 30 minutes from my home.

I still have some left if interested:
