A shell ring (7) is placed on the bottom mold (6) and forms the shape of the desired outer wall of the glass material together with the inner wall (6a) of the bottom mold (6), and a male shell ring (7) is placed on the bottom mold (6) and forms the shape of the desired outer wall of the glass material. Five molds consisting of plungers (8) as molds are prepared, and as shown in FIG. 6, molten glass (9) is placed inside the bottom mold (6).
As shown in FIG. 7, the plunger (8) is lowered to press the molten glass (9), thereby obtaining a symmetrical glass material aO) as shown in FIG.

生産コストが高くなる欠点があった。As described above, the method for manufacturing glass products described in the above-mentioned document involves combining a plurality of asymmetrically shaped glass products to form a symmetrical glass material, and after that forming, a plurality of asymmetrically shaped glass products are made from the above glass materials. The 1J manufacturing method has the advantage of producing high-quality glass products with good shape accuracy and no hot spots or wrinkles, but it has the advantage of being able to produce glass products of good quality with no hot spots or wrinkles. The scale does not require the five molds of the Plancider and Plancider, but requires equipment for placing the molten glass in the bottom mold, which has the drawback of increasing production costs.
