Abstract

PURPOSE:To simplify production and to reduce the percentage of flaws such as cracks by a method wherein a series of processes, including discharging air from, enclosing gas into and sealing the glass frit of a luminous vessel, are carried out in the same container for heating. CONSTITUTION:On a stand 19 contained in a container 18 of a vacuum heating furnace 17 capable of discharging air from, enclosing gas into and heating the container, a luminous vessel 20 which has been filled with glass frit in its opening is placed so that the opening looks upward. While the container 18 is being heated by a heater 21, the container 18 is vacuumized and, at the same time, the luminous vessel 20 is also made free from gas. Next the container 18 is filled with rare gases and the temperature of the heat supplied by the heater 21 is raised to exceed the melting point of the glass frit. By heating and melting the glass frit in the atmosphere containing the rare gases, the openings of the external and internal bodies of the vessel are sealed, and then the temperatured is reduced.
