Aside from their bulk, weight, and general messyness, has anyone done any
quantitative measurements on the lossyness of saltwater caps?

Any of you with impedance bridges?  Or even a pulse generator and a
digitizing oscilloscope?

Glass is the dielectric, and is traditionally considered lossy, but just
how lossy?
