Bronzeware
Bronzeware refers to a variety of utensils crafted from an alloy comprised mainly of copper and tin that were cast and forged in ancient China. When freshly cast, bronze has a golden hue. However, over time, it acquires a greenish-blue patina, especially after being buried underground.
The oldest known item of Chinese bronzeware is a knife uncovered at the Majiayao culture site in Gansu province, dating back roughly 5,000 years. The Bronze Age (c. 2100 B.C. - c. 500 B.C.) in China spanned the Xia (c. 2070-1600 B.C.), Shang (1600-1046 B.C.), and Western Zhou (1046-771 B.C.) dynasties and the Spring and Autumn period (770-476 B.C.), with the bronzeware cast in the Shang and Zhou (1046- 256 B.C.) dynasties being the best. Bronze casting reached its peak during the late Shang and early Zhou periods. The Siyang Fangzun, a square vessel with four goats, is the largest surviving bronze square vessel made during the Shang Dynasty, and the Simuwu Ding, a rectangular colossus with four legs, is the world's heaviest bronze item discovered to date. Both vessels represent a high level of development of the bronze-age culture during the Shang Dynasty.
In ancient China, bronzeware was a symbol of state power and was primarily used as sacrificial vessels during the Xia, Shang, and Zhou dynasties. The utilization of bronzeware was subject to complex and strict regulations based on an individual's rank and status, and the number and size of items varied according to their social standing. Bronzeware reflects the level of technological and artistic development of ancient Chinese civilization. It holds an important position in the history of ancient Chinese culture.
青銅器
青銅器是中國古代用銅、錫等合金經(jīng)燒制、鍛造后形成的各種器物，剛剛鑄造完成時呈金色，但因為埋藏地下時間長久，青銅表面氧化，產(chǎn)生銅銹后變?yōu)榍嗑G色，被稱為“青銅”。
中國已知最古老的青銅器是甘肅馬家窯文化遺址出土的青銅刀，距今約5000年。中國的青銅時代為夏、商、西周至春秋時期（公元前21世紀(jì)—公元前5世紀(jì)），其中商周時期的器物最為精美。商朝晚期到西周早期，青銅鑄造技藝達(dá)到巔峰。商四羊青銅方尊是中國現(xiàn)存商代青銅方尊中最大的一件；商后母戊鼎是至今世界上出土的體量最大的青銅鼎， 它們均代表了高度發(fā)達(dá)的商代青銅文化。
在中國古代，青銅器是國家政權(quán)的象征。在夏商周時期，青銅器主要作為祭祀的禮器，它的使用有繁復(fù)嚴(yán)格的等級規(guī)定，身份地位不同，所使用的青銅器數(shù)量和形制大小也不同。青銅器集中體現(xiàn)了中國古代生產(chǎn)技術(shù)和藝術(shù)發(fā)展的水平，在中國古代文明史中占有重要地位。
