The bronze mirrors unearthed in Shaanxi can still be used as a reference for people 2000 years ago. Why did the ancients use bronze mirrors?

The reason why the ancients used bronze mirrors is because the smelting process of copper is relatively mature and the economic value of copper is relatively low. A bronze mirror, also called a bronze mirror, is a mirror made of bronze as its name implies. Bronze refers to a metal alloy containing copper, tin (or lead) at the same time, and it is the earliest alloy smelted and put into use by human beings. This alloy has the advantages of low melting point and high strength. These two advantages further endow bronze with the advantages of easy casting and strong wear resistance. Based on these advantages, after the invention of bronze, the ancients in China began to cast various objects with bronze, and China also entered the bronze age.

As one of the bronze smelting objects, the bronze mirror was invented on the basis of the prevalence of bronze. Before the bronze mirror was invented, most ancient people in China used a kind of bronze mirror called? Supervision? Act as a mirror. So-called? Supervision? Do you use the principle of water energy to identify shapes and take pictures, that is? Mirror? In fact, it is a big basin full of water. At first, the ancients used it to make it? Supervision? Made of tile, after entering the Zhou Dynasty, the ancients began to cast with bronze. Due to the change of production materials, which mirror does this represent? Supervision? Became? Jane? .

Bronze mirrors in the early Shang Dynasty were mostly used as ritual vessels, so they were not widely used. After entering the Qin and Han Dynasties, the casting and use of bronze mirrors became common. Among them, in the Qin Dynasty, bronze mirrors had been cast in batches. While casting bronze mirrors in batches, the ancients made mirrors with gold, silver, iron and other materials. However, because the smelting process of copper is the most mature and the economic cost of adding copper is low, copper mirror is the main one. Compared with the short-lived Qin dynasty, the western Han dynasty is because? The rule of Wenjing? 、? Hanwu Shi Sheng? And then what? Zhao Xuan Zhongxing? With the arrival of many politicians, the production technology of bronze mirrors has been greatly improved. At the end of the Western Han Dynasty, bronze mirrors had become one of people's daily necessities.

After the Han dynasty, the production technology of bronze mirrors became more and more sophisticated. Especially in the prosperous Tang Dynasty, the ancients began to increase the tin content in bronze mirrors, so bronze mirrors became brighter and brighter. In addition, the Tang people added many new bronze mirrors on the basis of their predecessors. Because the bronze mirror has never met anyone who can compete with it? Opponents? Therefore, it has long been the most important photographic tool of the ancients. Later, until the Ming and Qing Dynasties, glass with better photographic effect began to appear, and bronze mirrors gradually declined. It can be seen that the reason why the ancients kept taking pictures with bronze mirrors was that they failed to find a more economical and practical substitute.
