Neodymium sodium borate glass bead NEW!
diameter ~ 12 mm – 1.1 – 1.3 grams
Material: Na Nd B Glas – Nd3+ (~ 20mol%)
This strongly colored glass changing its color from wine red to dark blue depending of the wavelength of the used light and viewing angle, is used in optics.
We are able to cast large rods with several cm diameter and lengths up to 50mm
Beautiful optical glass beads doped with metal ions.
Elaborately and individually manufactured by us in the laboratory from highly pure reagents.
Gorgeous beads showing the typical colors of different metal ions in different oxidation states.
They can be used for save demonstration of different colors of the metal compounds or just for collecting.
