To Engrave on Glass with Emery Powder
用金刚砂在玻璃上雕刻花纹

Cut a stencil of your design out a sheet of paper same size as sheet of glass. Glue this to glass, and affix the glass to bottom of a box with drawing pins. Pour in shots and emery powder. Put lid on and shake well with a circular motion. The shots will cause the powder to engrave the stencilled pattern indelibly on the glass.
找一张和想要雕花的玻璃一样大小的纸片，在上面剪出自己设计的花纹作为模板。把纸片粘在玻璃上，再把玻璃用大头钉固定在一个盒子的底部。在盒子里倒入烈酒和金刚砂。盖上盒盖，手臂做圆周运动摇晃盒子。烈酒和金刚砂发生化学反应，就能永久性的把图案刻在玻璃上了。
