PROBLEM TO BE SOLVED: To provide a turn mold blowing method of a glass product capable of forming a clear engraving pattern on a thin glass bottom part, and producing high-grade glass having a thin trunk.SOLUTION: A glass seed P is subjected to turn blow molding in a finishing mold by a rough mold. A glass product having a pattern formed on a bottom part is produced. The finishing mold 1 is constituted separably into a body mold 1A and a bottom mold 1B. After blowing the glass seed P into the finishing mold 1, only the body mold 1A is rotated in the state where the bottom mold 1B is fixed. The glass seed P is extracted, while rotating the body mold 1A.SELECTED DRAWING: Figure 1 【課題】薄いグラスの底部に鮮明な彫刻模様を形成することができ、胴部の厚みが薄い高級なグラス等を製造することができる硝子製品の廻し吹き製法を提供する。【解決手段】粗型で硝子種Ｐを仕上型内で回し吹き成形する。底部に模様を形成する硝子製品を製造する。仕上型１を胴型１Ａと底型１Ｂとに分離自在に構成する。仕上型１に硝子種Ｐを吹き込んだ後に、底型１Ｂを固定した状態で胴型１Ａのみを回転させる。胴型１Ａを回転させながら硝子種Ｐを抜き取る。【選択図】図１
