PROBLEM TO BE SOLVED: To provide a method and an apparatus for forming glass tumblers with drawn legs, by which the glass tumblers free from seam and each having a long leg part can be efficiently and continuously manufactured. SOLUTION: When the glass tumblers are formed by a burn off machine 1, the pedestal part 41 and the moil 42 of each glass product 40 to be shaped, having the moil, are held by a pedestal part holding mechanism 2 and a moil chuck mechanism 3, respectively, and at the same time, the leg part is heated while rotating the chuck mechanism 3 at a constant speed. Then, the pedestal part holding mechanism 2 is raised to extend and form the leg part 43, and thereafter, the moil 42 is cut and removed. In the shaping apparatus, the pedestal part holding mechanisms 2 with respective rotation driving mechanisms and the moil chuck mechanisms 3 are attached to the burn off machine 1, and a burner 4 for heating the leg part is provided at the lower part of each pedestal part holding mechanism 2, and further each pedestal part holding mechanism 2 is made vertically movable in the upward direction, in order to shape the glass tumblers.
