This is pendulum of an old Marti clock. Glass vials are sealed (by melting) and can't be opened. However they are dirty inside, seems like oxid. Is there a way to clean it without opening them?

I know of no way to do that. On the positive side, this clearly shows that it is a real mercury pendulum, not a fake one.

It is the compounds of mercury that are lethal, best to be happy it is all sealed and leave well alone. It will still work as intended.

I have a French Crystal Regulator with mercury vials in the pendulum also. Mine are a bit discolored, but not as bad as yours. I've wondered if a heat bath would help or has anyone ever tried putting a vial in an ultrasonic? If either caused a vial to break, it would be very messy and a bit of a toxic mess.

Mercury is very dangerous stuff! If dropped it can travel droplets for a long while.
As for putting a vial in an ultrasonic unit, would you put a stick of dynamite in the fire? :eek:

Remember the mad hatter in Alice ...

As has been said, you can't do anything about the discoloured mercury vials, but I would suggest that it would be good to clean up the three rusty support pillars, which would make the whole pendulum look a lot better.

I have a mercury pendulum with the same discoloured vials, but if the rest of the pendulum is clean, it does improve the overall appearance.
