摘要

PROBLEM TO BE SOLVED: To provide a method of manufacturing glass gob by which molten glass droplet can be suppressed from sticking to a lower die even when the temperature of the lower die is made high, and to provide a method of manufacturing the glass molded body and apparatuses therefor.;SOLUTION: A hydrocarbon gas atmosphere containing hydrocarbon gas is formed in the dropping passage of the molten glass droplets. The molten glass droplets are dropped to the lower die to be passed through the hydrocarbon gas atmosphere.;COPYRIGHT: (C)2010,JPO&INPIT
