Discoverer: Jean-Charles Gallissard
Place: Genf, Switzerland
Year: 1880

Discovered in 1880 by J.C. Galissard in Geneva, Switzerland, and isolated by P.E. Lecoq de Boisbaudran in 1886 in Paris, France. Gadolinium is a member of the lanthanide group of elements, and is obtained from the same sources as europium (its abundance in the Earth's crust is 7.7 ppm). It is a silvery white metal which is ductile and malleable. It is stable in a dry atmosphere but forms an oxide coating when exposed to moist air. It reacts slowly with water and is soluble in acids. Gadolinium has limited uses as a pure metal, but when alloyed with chromium, iron or similar metals, the resulting alloys have improved workability and corrosion resistance. Due to its magnetic properties, gadolinium is used in the manufacture of magnets, recording heads and electrical components.

3 large beads of neodymium-, praseodymium- and Erbium glass - NEW!

Diameter ~ 20 - 22mm - weight ~ 4.3 - 5g

Doping conc.:  5 mol% Er2O3, Pr2O3, Nd2O3

Material: BaP

Nice glass beads made of optical barium phosphate glass. Doped with praseodmyium- , neodymium and erbium oxide (5 mol% concentration each). Each one hand crafted. Since this kind of glass is produced very rarely and only in charges of several hundred kgs, it is a true opportunity to get it.
