During my Nixie tube project mercury will be a good solution for
prolonging the tubes' lives. When I merely mentioned the possibility
while talking to our facility manager, he wouldn't want to listen to me
anymore, and I had to assure that I would not tinker with mercury in
their rooms...
The background is that a couple of years ago someone spilled a whole lot
of mercury out of carelessness, and it was very expensive to get it all
cleaned. OK, I only need less than a drop per tube, so I really do not
see the harm, but what can you do...

They still put mercury in glass envelopes, there are several hundred
here where I work.
In the light fittings, 2 types high pressure and low pressure mercury.
and HID and metal halide.
Mercury is also present in reasonable quantity in fluorescent tubes,
of which there are millions all around us.

In the UK, in the days of pounds shillings and pence, LSD, a ha'penny
was very much the same size as a shilling. So lots of schoolboys
would break open a thermometer and coat the ha'penny with the mercury
to make it silver and pass it off as a shilling - 24 times the value.
Smearing the mercury on the coin with a finger, of course. I think
that's what they call liquid assets.
