The sleet pattern is a very complicated decorative pattern. Each of the sleet drops is different in size and grows gradually from the top to the bottom. To achieve that abundant and vivid texture, the craftsman hand-hammers each of the drops, and after thousands of hammer works the kettle will finally reveal its shape. The proportions and the arcs of the kettle also show a high standard of aesthetics. It brings pure enjoyment to its collectors and users.
