Klemm and Bommer first produced Erbium metal in 1934 by reducing the anhydrous chloride with potassium vapor. Erbium is on the rare-earth elements and is found in the same minerals as Dysprosium.   The metal is fairly stable in air and does not oxidize as quickly as other rare-earth elements. Erbium oxide is often used as a decorative touch on porcelain in which it is used as a glaze.
