    • A method of making a quartz-shell drum includes the steps of heating a quartz tube to a temperature at least sufficient to enable quartz to flow. A diameter of a portion of the heated quartz tube is enlarged to a predetermined size. The enlarged tube is cut perpendicular to a longitudinal axis to create a shell having a desired height. A top edge and a bottom edge of the shell are ground to form smooth radii. The top and the bottom edges are fused to create top and bottom rounded edges. In an alternate embodiment, the top edge is instead formed to be inwardly angled. Finally, a top and a bottom head are affixed to the top and the bottom edges, respectively, to form a drum.
    • 制造石英壳滚筒的方法包括以下步骤:将石英管加热至至少足以使石英流动的温度。 加热的石英管的一部分的直径被扩大到预定的尺寸。 将放大的管垂直于纵向轴线切割以产生具有期望高度的壳体。 将外壳的顶部边缘和底部边缘磨碎以形成平滑的半径。 顶部和底部边缘被熔合以产生顶部和底部圆形边缘。 在替代实施例中,顶部边缘被形成为向内成角度。 最后,分别将顶部和底部的头部固定到顶部和底部边缘以形成鼓。
