青铜器（Bronze Ware）在古时被称为“金”或“吉金”，是红铜与其他化学元素锡、铅等的合金，其铜锈呈青绿色。
青铜器的使用开始于新石器时代晚期的土耳其和伊拉克地区，及叙利亚古代TellRamad遗址出土的铜珠等 。中国青铜器开始于马家窑至秦汉时期，以商周时期的器物最为精美。 在中国仰韶文化早期和马家窑文化时期就已经出现。
中国最初出现的是小型工具或饰物。夏代始有青铜容器和兵器。商中期，青铜器品种已很丰富，并出现了铭文和精细的花纹。商晚期至西周早期，是青铜器发展的鼎盛时期，器型多种多样，浑厚凝重，铭文逐渐加长，花纹繁缛富丽。随后，青铜器胎体开始变薄，纹饰逐渐简化。春秋晚期至战国，由于铁器的推广使用，铜制工具越来越少。秦汉时期，随着陶器和漆器进入日常生活，铜制容器品种减少，装饰简单，多为素面，胎体也更为轻薄。
中国青铜器制作精美，在世界青铜器中享有极高的声誉和艺术价值，代表着中国5000多年青铜发展的高超技术与文化。

英文翻译：Bronze Ware, called "gold" or "gold" in ancient times, is an alloy of red copper with other chemical elements such as tin and lead. Its copper rust is bluish green.
The use of bronze ware began in the late Neolithic Age in Turkey and Iraq, and the ancient TellRamad site in Syria unearthed copper beads. Chinese bronzes began from Majiayao to the Qin and Han dynasties, with the most exquisite ones from the Shang and Zhou dynasties. It appeared in the early period of Yangshao culture and Majiayao culture.
China first appeared in small tools or accessories. The Xia dynasty began to have bronze vessels and weapons. In the middle period of shang Dynasty, bronze ware varieties were abundant, and inscriptions and fine patterns appeared. From the late Shang dynasty to the early Western Zhou Dynasty, bronze ware was in its heyday, with various types, thick and dignified, gradually lengthened inscriptions and elaborate patterns. Later, the bronze body began to thin, gradually simplified ornamentation. From the late Spring and Autumn period to the Warring States period, copper tools became less and less due to the popularization of iron ware. During the Qin and Han Dynasties, with the introduction of pottery and lacquer into daily life, the variety of copper vessels was reduced and the decoration was simple. Most of them were plain and the body was thinner.
Chinese bronzes are exquisitely made and enjoy a high reputation and artistic value among bronzes in the world, representing the superb technology and culture of Chinese bronze development over 5,000 years.
