PROBLEM TO BE SOLVED: To provide a method for manufacturing a glassware capable of easily performing processing work such as decoration molding of a glassware having a hollow portion. SOLUTION: Softened glass 29 is wound around the outer diameter of a coil 21, subjected to decoration molding and solidified. Then, a supporting iron core 23 is pulled out of the coil 21, and the coil 21 is pulled out of the solidified glass 29. Thus, a hollow portion 31a of an eye bead 31 is formed. As the glass 29 attaches to the coil 21 along the irregularity of the diameter of the coil 21, a bonding strength between the coil 21 and the glass 29 is high. Therefore, force applied to the glass 29 during the decoration molding work does not hardly break the bonding between the coil 21 and glass 29. On the other hand, the coil 21 can be easily pulled out of the solidified glass 29 by reducing the coil diameter by twisting the coil 21 or the like after the supporting iron core 23 is pulled out of the coil 21.
