Erbium was discovered in 1843 by Swedish chemist Carl Gustaf Mosander, who detected it as an impurity in yttria.

Using ammonium hydroxide he precipitated fractions of different basicity from yttria.

In these fractions he found that the fraction that contained the pink color was erbium. Erbium was named after Ytterby, a town in Sweden 83 From the German word "bisemutum"

Erbium is considered to be moderately toxic
The highest concentration of erbium in humans is in the bones
Erbium is used in photographic filters to absorb infrared light.

Erbium oxide gives a pink color and has been used as a colorant in glasses and porcelain enamel glazes.

It is also used in nuclear technology in neutron-absorbing control rods.

Erbium is used in alloys especially with vanadium to decrease the hardness of metals.
