How long did you run them in before hitting them with high voltage?

Old Mercury Vapor tubes should be run with the filament but no high voltage for a number of hours before using. The mercury in old stored and shipped tubes is splattered all over the tube, on the plates and filament where it does not belong. Mercury is a pretty good conductor and should not be where it is not supposed to be.
