Colombium is not my name so says the IUPAC
instead they gave the name Niobium to me
a type two superconductor active in magnetic fields
especially adept at strengthening the welds between steel

I've got the deepest penetrating magnetic field of all the elements
Niobium ring around superconductors at cryogenic temps
physiologically inert for hypoalergenic jewelry
increasing the refractive index of glass to make thinner lenses so you can see

I've only been Niobium since 1950
preceded by 100 years of elemental controversy
old habits die hard so I still respond to Colombium
the name that's only used if you're a gringo American

I've got the deepest penetrating magnetic field of all the elements
Niobium ring around superconductors at cryogenic temps
physiologically inert for hypoalergenic jewelry
increasing the refractive index of glass to make thinner lenses so you can see

Nb-92 Nb-93
I'm encountered by most people only very rarely
the daugther of Tantalus in greek mythology
Niobe's claim to fame is that she sired 14 kids
which they refer to as the Niobids
Colombium
Niobium
