Have you ever found that some cities with long history usually build museums, while emerging cities will never have museums?

Museums are places to record the development of a country in different periods. We can really know what stage people's lives and articles used at that time have reached through the collections in the museum. These collections contain the crystallization of human wisdom and the footprints of civilization and progress for thousands of years. Therefore, some schools will organize students to visit museums to enrich their extracurricular knowledge.

1, the front is corroded by years.

The craft of ancient bronze mirrors is incomparable to modern ones. In order to reflect people's faces, ancient craftsmen put a layer of tin amalgam on the front of the mirror after making it, and finally polished it with white enamel. However, even so, the role of bronze mirrors is still limited, and bronzes are difficult to resist the erosion of time. Therefore, most of the bronze mirrors are uneven, forming gray or green rust and mottling, which leads to the oxidation of most unearthed bronze mirrors.

2. The back is very valuable

The back of ancient bronze mirrors is usually well-made and has very beautiful patterns. Don't underestimate these patterns. It is precisely because of these distinctive patterns that archaeologists can judge which dynasty the bronze mirror was unearthed in. Not only that, but the layout on the bronze mirror is also extremely exquisite.

In ancient times, mirrors were not only used to reflect appearances. Some mirrors have been used for religious or other purposes, but no matter what kind of mirrors, they all have a common feature, that is, strong artistry, so the ornamental value of the back of bronze mirrors is very great.

In fact, these are all folklore. The main material of bronze mirror is copper. Buried in the ground for so many years, it has long been oxidized. The effect was not so good, let alone after being oxidized. Therefore, the unearthed bronze mirror has long lost its function of illuminating people, and there is nothing to see even in the face of tourists. The back of the bronze mirror is generally decorated with patterns, which is not only exquisite, but also reflects the characteristics of that era, which is what cultural relics lovers want to see, so the bronze mirror is just a simple back display.
