The bitter heart of the people is not worthy, and the three thousand Yue Jia can swallow Wu. Yue Wang Gou Jian is a well-known figure in the ancient history of the mainland, and the Yue Wang Sword is the personal sword of Yue Wang Gou Jian. This sword has been baptized for thousands of years, but when it was unearthed, it did not rust, why is this?
According to the relevant information. This Yue Wang sword was successfully excavated in 1965 in the Wangshan Chu Tomb Group and belongs to the bronze sword of the Spring and Autumn Period. It is said that this sword is engraved with a tongkan character, indicating that it is the sword of the Yue King. Later, this sword was also known as the world's first sword. This ancient sword is 55.6 cm, the body length is 47.2 cm, the width is 4.6 cm, the top length is 8.4 cm, and the weight is 857.4 grams, which is extremely delicate.
One of the reasons why the Yue Wang sword does not rust is the special crafting ingredient of the sword, this black bronze sword its main ingredient is copper. Among chemical elements, we know that copper is one of the least active metal elements. Under everyday conditions, it is not as easily oxidized as iron and aluminum. If there are no special circumstances, it will always remain in its original state without rusting. More importantly, the sword spear of the Yue King's Gou Jian contains a lot of copper, and the toughness of the sword is good and will not break. The high tin content of the blade part increases the hardness of the sword and makes the sword sharp. That is to say, in ancient times more than 2,000 years ago, the mainland has initially mastered the composite process of metal casting, which is really surprising.
The second reason why the Yue King Sword does not rust is the well-sealed storage environment. The Yue King's sword was buried deep underground and placed in a closed burial chamber before it was unearthed. The burial chamber is surrounded by delicate white ointment mud, which is compacted as a whole, making this burial chamber an almost confined space, closed with the gas exchange from the outside world, and the air cannot enter, which may be an external factor that Yue WangJian did not embroider in 2000. According to another person involved in the excavations at the site, the burial chamber where the Yue Wang Sword was buried was immersed in groundwater for a long time, almost completely isolated from the air. We all know that rust has two necessary conditions, water and oxygen are indispensable. In the case of complete isolation from oxygen, the metal is very poorly movable and cannot participate in the reaction. Copper is also a very inactive metal, in this case, there is no condition for rusting.
The above is a more reliable statement of the Yue Wang Sword in 2000. In short, it was unbelievable that the sword could be forged in that era and had not rusted for more than two thousand years. Of course, what attracts us is the touching historical story behind this sword.
