In 2000, the bronze mirror is still visible, what is the copper mirror made of?

In fact, in ancient times, there were many steps in the production process of copper mirrors, and each step had strict standards. If there is a defect in a process, it will affect the quality of the copper mirror, and even defective products, resulting in losses. The bronze mirrors of the Warring States, the Han Dynasty and the Sui and Tang Dynasties, in the course of 4,000 years of history, were the most well-made, and were the products of the social and economic prosperity at that time, and were diligently sought after by collectors.

After the Song and Yuan dynasties, due to the lack of refining, its historical reasons should be related to the loss of some key casting processes.

In recent years, with the heating up of the collection fever and the in-depth study of ancient bronze mirrors, we have gradually gained a comprehensive scientific analysis and understanding of the casting process of ancient bronze mirrors. Those who are interested in the collection of copper mirrors must have a comprehensive understanding of the casting process of copper mirrors, master the whole process of copper mirror production, and use theory to guide practice. Only with the support of perseverance, can we slowly enter the collection world, so that no matter from theory or practice, we can have a correct judgment on the identification, generation, repair, and identification of counterfeits of bronze mirrors.

Copper mirrors are usually made from copper-tin-lead alloys. Due to the strong plasticity of copper, the tensile properties of tin are good, which can improve the hardness and luster of copper mirrors. The proportion of liquid lead is large, and after alloy treatment, the surface of the copper mirror can be uniform and regular, not easy to deform, and the decoration is clearer, smoother and natural.

Therefore, the production process of the Tang Dynasty bronze mirror is not only very exquisite, but also very scientific in terms of alloy formula. According to the known alloy ratio in the Tang Dynasty bronze mirrors, copper accounts for about two-thirds, tin and lead together account for one-third, and their cross-sections are mostly silvery-white or pale yellow, which is a clear feature.

In addition, the craftsmen of the Tang Dynasty bronze mirror not only mastered the metal formula of the copper mirror, but also used special technology to produce many exquisite copper mirrors with their rich imagination and extraordinary creativity, such as gold and silver flat mirrors, luodian mirrors, etc., which fully showed the high level of development of the Tang Dynasty bronze mirrors, and the level of craftsmanship was really amazing.

In 2000, the bronze was thrown into the light, the bronze mirror is made of bronze, why the bronze mirror can be like a mirror to others, it all depends on the bronze training technology of the ancients is very developed, in order to create such a perfect bronze mirror.

It is usually made of pure red copper and tin, or lead or zinc, through special processing.

Bronze mirrors are usually made of copper, tin, lead, and other metals, with copper typically having a ratio of 70 and being slightly different for each cycle. The earliest bronze mirror was invented in Egypt, and China mastered this technology during the Shang Dynasty.

The poets of the Tang Dynasty also raised their shirts to the mirror many times, "Xiaojing but sad clouds and sideburns change, and the night chant should feel the cold moonlight", "Flying mirror under the moon, Yunsheng knot Hailou", "I didn't expect that in the Ming Realm, the shadows pity each other", whether it is the mirror in the oil painting or the mirror in the famous poemIt is all bronze mirrors, not contemporary mirror glass. The ancient people mixed copper, iron, silicon, aluminum and some uncommonly used metal materials such as tin, lead, zinc, etc. according to a certain ratio, put them in the melting furnace to melt, turn them into metal material juice and pour them into the mold shells prepared in advance, and after condensing and cooling, it became the development process of copper mirrors. It must be noted that most of the bronze mirrors in ancient times were ring-shaped, one side was a mirror, and one side was hand-carved with various patterns, which meant auspiciousness.

Contemporary people feel that the copper mirror is not clear on the one hand, it is a fraud in film and television dramas, and on the other hand, the history books in the history museum usually only show that the copper mirror is not clear, and it looks thick and unclear. We often ignore that after thousands of years of tempering, the infiltration of the soil layer, the air oxidation of the gas, and the variability of the material of the metal material itself will make the originally bright mirror glass more and more embroidery, green and black. After taking out the first product from the mold, there will be a professional craftsman to carry out physical polishing on one side of the ring copper until the light of the mirror glass grinding can be seen, in the past, some people tried to polish the contemporary copper 5 jiao coin, and the round piece of the grinding out is already very clear.

From ancient times to the present, everyone has a love for beauty, and in ancient times, when going out, it was necessary to comb their own makeup, and now there are mirrors, and in ancient times, there were also bronze mirrors. Before the invention of the copper mirror, everyone was to use the reflection in the water to see their own appearance, after the invention of the bronze ware, we should use the copper basin to fill the water to illuminate themselves, with the improvement of the copper smelting process, we gradually began to use copper or tin to make copper mirrors. In ancient times, the copper mirror was made according to the copper smelted out, the copper mirror was a necessity for everyone's daily life at that time, the copper mirror was exquisitely produced and manufactured in ancient times, with a different shape, and it was also the historical and cultural heritage of ancient China.

The ancient mirror is the meaning of a small basin, because everyone has been using the basin to fill water to shine on themselves, the mirror in ancient times was called a prison. At the beginning, it was in the Shang and Zhou dynasties, gradually casting copper mirrors, along with the improvement of smelting technology, to the Qin Dynasty, gradually a lot of copper mirrors were produced, because the copper mirrors were better than the mirrors, so from the Qin Dynasty will no longer apply water in the Jian, and then in the Spring and Autumn PeriodThe application of copper mirrors or travel rulers is more common, and the mirrors made by upgrading the processing technology are also more exquisite. In ancient times, copper mirrors were smelted and melted according to strict proportions such as copper and tin, or lead, and then poured into abrasives to produce blanks after refrigeration, and then after production and processing, the surface was coated with tin and mercury.

It is not possible to be as smooth as new, because the ancient copper mirrors are made of copper, which is generally burned at high temperature, and then let the craftsman finalize the mirror surface.

The material of the bronze mirror is different, and I think that even if it has been buried underground for thousands of years, it can be as clean as new, because its material is still very good.

After the bronze mirror is buried in the ground for thousands of years, it can still be as clean as new, and the ancient bronze mirror can be made after countless polishing.

Ancient copper mirrors were made of copper and polished, and now the mirrors are made of glass, and I still think that modern mirrors are more clear.

This difference is really big, after all, the materials used in copper mirrors and current mirrors are completely different, and the clarity of the light is also different.
