摘要： According to a method of molding a glass body, a glass preform is placed between upper and lower molds of a mold assembly. The mold assembly is then heated to a predetermined heating temperature falling within a heating temperature range corresponding to a glass viscosity range of the glass preform of 10.sup.8 to 10.sup.10.5 poise. A pressure high enough to mold the glass preform is applied between the upper and lower molds when the glass preform is at the predetermined heating temperature, so that an unfinished glass molded body is formed. The pressure is released, and the unfinished glass molded body and the mold assembly are gradually cooled to a temperature within a glass viscosity range of 10.sup.11.5 to 10.sup.14 poise while the unfinished glass molded body is held in the mold assembly. A glass molded body is then released from the mold assembly.
