It may not be necessary to open a tube to renew the supply of an
alkali metal.
I remember an experiment where an incandescent light bulb was dipped
into molten sodium chloride in an iron vessel.
The filament was run and a voltage between the filament and the iron
vessel caused sodium ions to migrate through the glass
into the bulb. Sodium accumulated in the bulb.
It is obviously a slow process, but then you did not need to put much
Cs in the bulb.
Why not use it to recharge an alkali metal lamp?

Now that we are discussing how to restore Rb lamps.
Has anyone given any thought to refilling or refluxing the Cs in
depleted Cs tubes?
Obviously opening would require high vaccum equipment - which is a
totally separate category of nut (Or is it?)
