FOV: 6" wide.

Frozen melted salt containing home made phosphors based on Group II sulfides.

From left to right....

Back row (Group 2 or IIA):
...Jackolite (CaS:Mn,Pb in salt),
...Sunnylite (SrS:Mn in salt),
...Baloneystonite (BaS:Cu in salt)

Front row (Group 12 or IIB):
...Sphalerhalite (ZnS:Cu,Mn) melted on copper plate,
...Sphalerhalite (ZnS:Cu,Mn) melted in Al tray on steel plate,
...Sphalerhalite (ZnS:Cu,Al) melted on limestone slab
