青铜鼎中圆鼎的制作工艺

圆鼎的铸造工艺具有很强的纵向可比性；同时，圆鼎又是当时最具有代表性的器物，它的铸造工艺应该代表了一个时期青铜器冶铸工艺的主流，现在一次来说一些关于青铜鼎中圆鼎的铸造工艺吧。

The casting process of round tripod has strong longitudinal comparability; At the same time, the round tripod was the most representative utensil at that time. Its casting process should represent the mainstream of bronze smelting and casting technology in a period. Now let's talk about the casting process of round tripod in bronze tripod.

1、锥足圆鼎：此鼎斜折沿、厚方唇、拱形立耳微外移，下部微鼓，圆底。口唇饰燕尾纹一周，双耳外侧饰龙纹。初始系浑铸成形，后因鼎足出现浇不足缺陷而再次浇注，致使空足与腹腔不连通。3块腹范与1块腹芯组成铸型。3块腹范沿三足外侧中线分型。足部、足腹连接处及腹部纹饰上的铸造披缝明显。腹芯与三足芯、芯合为一体；沿二足倒立浇沣成形。腹部及口沿外的纹饰为模作纹，足似范作纹。鼎腹可见一形状不规则的。

1. Conical foot round tripod: This tripod has a slanted fold edge, thick square lips, arched vertical ears and a slightly outward shift, with a slightly drum at the lower part and a round bottom. The lips are decorated with swallow tail, and the outer sides of the ears are decorated with dragon patterns. Initially, it was formed by muddy casting, and then it was poured again due to the insufficient pouring defect of the tripod foot, resulting in the gap between the empty foot and the abdominal cavity. Three web molds and one web core form the mold. Three abdominal models were classified along the midline of the lateral side of the three feet. The casting drapes on the foot, the joint of the foot abdomen and the abdominal decoration are obvious. The abdomen core is integrated with the tripod core and core; Pour and shape along the two feet. The patterns on the abdomen and outside the mouth edge are patterned, and the feet are patterned. An irregular shape can be seen in the belly of the tripod.

2、弦纹锥足圆鼎：此鼎斜折沿，方唇，口部变形，故形状不甚规则。拱形立耳，深腹，壁较薄，圜底。三空锥足与腹腔通。耳足呈四点试配置。上腹部外壁有不规则的凸弦纹三道，余均素面。

2. String pattern cone foot round tripod: This tripod has an oblique fold edge, square lips, and deformed mouth, so its shape is irregular. Arch shaped ears, deep abdomen, thin wall, round bottom. The three hollow cone feet connect with the abdominal cavity. The ears and feet are arranged in four points for trial. There are three irregular convex chord lines on the outer wall of the upper abdomen, and the rest are plain.

圆鼎的制造工艺难度比方鼎要小得多，所以直接造成了圆鼎无论在数量上，还是在造型上都要远远多于方鼎。不管是圆鼎还是方鼎，都是是我们国家5000多年历史文明的见证，也是文化的载体。

The manufacturing process of round tripod is much less difficult than that of square tripod, so the round tripod is much more than square tripod in terms of both quantity and shape. Both round and square tripods are the witness of our country's 5000 year history and civilization, as well as the carrier of culture.
