Could a column of mercury inside a tube of glass be used as an

OK Cecil I'll bite. Yep! [I think there may be a Troll here :-) ]

Mercury is a metal, albeit a dangerous one. It has a resistivity about
55 times that of copper. To a first approximation it's thermal
coefficients are within a factor of 2 or less. It's location in the
electrochemical series indicates that the relative potential between
copper and mercury of -0.4546 volts would be subject to corrosive
effects. Coupling RF to the column would require indirect coupling such
as inductive.

Why in Heaven would you or anyone want to do it? [I think there may be a

Glass is an insulator and has dielectric properties.

My conclusion: Yep! But it would have much higher losses than copper
