The wire was threaded through ceramic beats, then placed inside of a ceramic tube, then placed in a larger grey-black outer tube (SiC, maybe?). Used for temperature control in soaking-pit furnaces in the blooming mill. That particular summer taught me how much dry heat a human could take in short doses--the next year, a co-worker collapsed and died while changing a thermocouple. Anyway, the thermocouples got bumped during loading and unloading the furnaces and were broken pretty often. When repairing a thermocouple, on of the goals was to butt-weld any wire pieces together. A job that I couldn't do. Cheers, Chuck .
