March 28, 200818 yr Is there a way to tell the temp rating on a unknown refractory, and if you exced its rating, what will happen? I ask because I have a box of 12"x12" boards of some kinda of fiber refractory from the 70's, just curious as to what they are. -Andrei
March 29, 200818 yr If It's From The 70's You Will Deffinantly Lose Brain Cells! I REALLY HAVE NO IDEA; SORRY!!
March 29, 200818 yr You could try finding a soils lab in your area, buddy up with one of the employees, owners, etc. and see if they'll let you test sample pieces in a muffle furnace. Paying them to test it would cost more than just buying a known refractory. Of course buying new would eliminate the guesswork . . . What fun is that? Frosty

March 29, 200818 yr That's a good find. I reckon what I'd do is coat with ITC100 in case there's nasty lung worms inside, put a piece of steel on a chunk of it, and lay into it with a torch. See who melts first.
