Very early tubes used magnesium, Scientific American
had a great project using a Model T ignition coil to
turn one into an X-Ray source which refered to them as being old way back then.
I remember reading the original article and was sore tempted to build
the rig, but was a little scared about the X-rays. Not too long
before that time, it was still possible to pick up a junked shoe
fluoroscope to do the same thing a little better.
I've long wondered about using a HV rectifier tube as a source of
soft X-rays, though.
