    • A method for making perforations or forming depressions in a glass work piece is described. Pursuant to the method, a two piece housing for the work piece is provided. The housing when assembled has a cavity conforming in size and shape to the work piece. The lower housing piece has a continuous upper surface and the upper housing piece has a smooth lower surface and openings in the housing piece conforming in size and position to the perforations or depressions desired to be made in the work piece. The work piece is enclosed in the housing and then plugs are inserted in the openings in the upper housing piece. The plugs snugly fit the openings and extend above the upper surface of the upper housing piece. A weight is then disposed on the upper surface of the plugs. The weight may be a flat metal sheet and is of sufficient weight to cause the plugs to exert a pressure of at least about one half pound per square inch on the work piece. The resulting assembly is then subjected to a temperature intermediate the softening point and the working point of the work piece and the temperature is maintained until descent of the plugs into the work piece ceases. The assembly is then cooled to ambient temperature, the work piece is removed from the housing and then the plugs are removed from the work piece.
    • 描述了在玻璃工件中进行穿孔或形成凹陷的方法。 根据该方法,提供了用于工件的两件式外壳。 组装时的壳体具有与工件尺寸和形状相符的空腔。 下壳体件具有连续的上表面,并且上壳体件具有平滑的下表面,并且壳体件中的开口在尺寸和位置上符合期望制成在工件中的穿孔或凹陷。 工件被封装在壳体中,然后将插头插入上壳体件的开口中。 插头紧密地装配开口并且在上壳体的上表面上方延伸。 然后将重物设置在塞子的上表面上。 重量可以是平的金属片材,并且具有足够的重量,以使塞子在工件上施加至少约一磅半平方英寸的压力。 然后将所得的组件经受在工件的软化点和工作点之间的温度,并保持温度,直到插头进入工件的下降停止。 然后将组件冷却至环境温度,将工件从壳体中取出,然后将塞子从工件中取出。
