摘要： Disclosed herein is a glass whose viscosity index (A) defined as a value obtained by dividing the viscosity of the glass at the liquidus temperature thereof by the liquidus temperature of the glass is in the range of 0.0004 to 1.5. Such a glass is melted in a melting furnace equipped with a nozzle, and the molten glass is dropped from the nozzle intermittently and regularly to obtain glass droplets. The glass droplet naturally dropped from the nozzle is received by a receiving mold to form a glass gob. The glass gob can be used as a preform for reheating molding. Further, it is possible to produce an optical glass element having no plane defect such as a shear mark by press-molding a hot glass gob with an upper mold just after the glass gob is received by the receiving mold.

摘要： A manufacturing apparatus of the present invention has a pair of dies that form each cylindrical surface, and a plane member that forms side surfaces of an element. The upper die and the lower die has a cylindrical surface which is worked so as to have generatrix which connects intersection points between a non-arc axis and a cylindrical section and between an arc center axis and the cylindrical section. The plane member is pressed against reference surfaces of the upper die and the lower die. In this state, a glass material is put between the upper die and the lower die, and a distance between the upper die and the lower die is decreased. As a result, the cylindrical surfaces of the upper die and the lower die and the plane of the plane member are transferred onto the glass material.
