A METHOD OF ENCAPSULATING A RESISTOR ELEMENT COMPRISING THE STEPS OF: ASSEMBLING A RESISTOR ELEMENT HAVING FLARED METAL CAP MEMBERS ATTACHED TO EACH END THEREOF WITHIN AND CO-AXIAL TO A GLASS MEMBER, SAID GLASS MEMBER EXTENDING THE LENGTH OF SAID RESISTOR ELEMENT AND BEING IN CLOSE PROXIMITY TO SAID FLARED PORTION OF SAID END METAL CAP MEMBERS, HEATING SAID RESISTOR ELEMENT AND GLASS MEMBER ASSEMBLY BY PASSING IT THROUGH A HEATED REDUCING ATMOSPHERE AT A TEMPERATURE SUFFICIENT TO SOFTEN THE GLASS AND CUASE THE GLASS ADJACENT SAID METAL CAP MEMEBERS TO COLLAPSE DUE TO THE HIGHER GLASS TEMPERATURE IN THE PROXIMITY OF THE METAL CAP MEMBERS, THEREBY CAUSING SAID MELTED PORTIONS OF SAID GLASS MEMBER TO COLLAPSE, CONTACT THE METAL CAP MEMBERS AND FORM A GLASSTO-METAL SEAL THEREWITH, AND COOLING SAID ASSEMBLY TO PREVENT THE COLLAPSE OF THE REMAINING PORTION OF SAID GLASS MEMBER.
