Glass bead made of pure Manganese (IV) phosphate – Magnetic glass
Size about 13mm – weight ~ 1.2 – 1.4 grams
Material: Mn3(PO4)4 ~ 50 mol% Mn4+
This glass is attracted to a neodymium magnet.
Nice optical glass bead. 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.
