How do you tell when a nipple is burned out and needs to be replaced?
I think/hope we finally got smart-enough to actually look at them occasionally.

i think that material is called ampco or something like that.
Unless something has changed the Ampco nipples and touchhole liners are made of Beryllium, which is very heat resistant and they will not burn out as fast as a stainless steel nipple or touchhole. they look like brass but are much harder to file or work.
