Barium metal 99.8%

from 5.00

To many barium will sound vaguely familiar but, like calcium, few will know that it's actually every bit a metal as iron or gold. This metal has a particularly voracious appetite for oxygen. So much so that its only commercial usefulness in pure form is to mop up errant oxygen atoms where they're unwelcome. This used to be a big job in the making of vacuum tubes but since the transistor came along barium was pretty much put out of a job. Well, except fort those barium enemas...

Due to the extreme ease with which it forms oxides, barium is quite possibly THE most difficult element to maintain in a shiny, polished state like normal metals can. So the choices are bare pieces of metal in oil with some oxidation or bare pieces of lustrous metal locked away in glass.
