Terbium Sodium borate glass bead.
Terbium Sodium Borate glass with over 40 mol% Tb3+! The glass shows a light orange colour under daylight and still illuminates green under 365nm UV. This is also the strongest magnetic glass we have produced so far.
Size about 12mm . Material: NaTbB
Each one handmade in our lab.
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.
