Don't confuse Globar thermistors with Globar resistors. The latter are non-inductive power resistors often used in dummy loads and parasitic suppressors.
My dummy load is made up of a dozen 600 ohm 150 watt Globars. Each one is about 18" long and 1" in diameter. Supposedly you can heat them to a dull red glow without hurting them, but I have never tried running that much power, and I'm not sure what such abuse would do to the resistance. I have heard of the ones used in parasitic suppressors of high power BC transmitters (50 kw) glowing under parasitic conditions.
