## Spouts: The shape of the spout should be adapted according to the different design varieties. Traditional spout shapes are divided into single-curve spouts, double-curve spouts, and triple-curve spouts. For example: "Pomegranate Ball," "Imitation Drum," and "Lotus Seed" have single-curve spouts; "Persimmon Round," "Han Platinum," and "Han Jun" have double-curve spouts; "Longevity Star" and "Western Barrel," although they are double-curve spouts, are actually formed with three curves when shaped; "Flat Bottom," "Auspicious," and "Papaya" have triple-curve spouts. The most common problem with single-curve spouts is that the upper and lower contour lines don't correspond, causing the area near the spout base to appear thin, creating the impression of a handle section. The correct contour line should be such that the back line of the spout follows a circular arc segment. This is not only aesthetically pleasing, but also allows room for selection when cutting the spout, and facilitates variation when carving the spout. The upper base area of a single-curve spout should be cut and carved firmly. The reason the lower base develops a handle-like appearance is that when cutting the spout, one doesn't dare to trim it sufficiently for fear that the spout opening won't fit, resulting in mounting it too low and creating a handle effect at the lower spout base. When carving a concealed spout on a single-curve spout, the two sides should show carved harmony when viewed from the side, and should appear in a /\ shape when viewed from the front, not appearing thin.
