When jade is first cut, iron is forged into a circular disk. A basin of water mixed with sand is prepared, one steps on the disk to make it rotate, adding sand to cut the jade until it is gradually severed. China's jade-cutting sand comes from Yutian in Shuntian and Xingtai in Zhending. The sand does not come from rivers but flows out of springs, fine as flour. Used to cut jade, it never wears out.
