Abstract

PURPOSE:To improve the yield by inflowing a hot inert gas into a glass thin tube in order to suppress the cooling effect on the heated portion of the glass thin tube due to the inert gas flow after a luminous material is introduced into the glass thin tube. CONSTITUTION:A rare gas introducing nozzle 8 which is connected to a rare gas feeding source is coincided on an extended line from the center axis of the glass thin tube 1 after mercury is introduced into the glass thin tube 1 as a liquid metal. A heating device 9 such as a sheathed heater is provided sround a part of the periphery of the rare gas inrroducing nozzle 8, a hot rare gas such as argon heated with the device 9 is inflowed ito the glass thin tube 1. Thus air in the glass thin tube is substitued by argon. And then the end of the opening of the glass thin tube 1 is sealed.
