My appreciation to those who responded to my question.  I tried the furnace 
cement and it worked fine as predicted.

  Subject: Replacement of plate caps on glass tubes


  I have some old glass tubes where the plate cap bond to the glass envelope 
has become loose; i.e. the cap is being held on by the soldered wire going 
through the glass envelope to the internal plate.  The solder joint from the 
wire connection to the plate cap is intact and the tubes are good, but the bond 
to the glass has failed over time.  Can the caps be unsoldered, re-bonded and 
re-soldered?
  Thanks for any help.
