Meteorite is a special kind of rock falling from outer space on the earth's surface. It is a precious and rare physical specimen for human beings to understand the stars in the solar system, which is of great research and collection value.

Those with large stone content are called meteorites (the largest number), those with iron content above 80% are called meteorites, and those with nickel content above 10% are called nickel-rich meteorites. Because of its high content and uniform distribution, ferronickel can be directly smelted to provide the earliest iron used by human beings. As early as 5,000 years ago, the ancient Egyptians knew that meteorites falling from the sky were mined to make cold weapons and iron bead jewelry.

1972, an iron-edged bronze cymbal was unearthed from the Shang Dynasty (BC14th century) site in Taixi Village, Gaocheng City, Hebei Province. Total graupel residual length 1 1. 1 cm, diaphragm width 8.5 cm, outer edge broken, residual edge covered with copper about 1 cm, completely oxidized. According to expert appraisal, the residual blade has no characteristics of artificial iron smelting; The distribution of nickel shows that the blade is made of meteorite and cannot be obtained by artificial iron smelting.

So far, four bronze weapons with meteorite blades have been unearthed in China. 1 piece of meteorite-edged copper cymbal was unearthed from Shang tomb in Pinggu county, Beijing. Residual length 8.4 cm, rectangular, up and down. The iron blade is embedded in the cymbal about 1 cm, which has been completely corroded.

The other two pieces are 193 1 year, an iron-edged bronze cymbal and an iron-assisted bronze ge unearthed in Xun County, Henan Province. The former is 17. 1cm in length, 10.8cm in width and 437.5g in weight; the latter is 18.3cm in length, 7cm in width and 378.5g in weight. It is now in the friel Art Museum in Washington, DC.

Ten famous swords refer to Xuanyuan Sword, Zhanlu Sword, Chi Xiaojian, Taiya Sword, Longquan Sword, Ganjiang Sword, Moxie Sword, Yuchang Sword, Chunjun Sword and Cheng Yingjian. The records of ten famous swords are mostly found in ancient books or legends, such as Historical Records, Yuejueshu, Liezi, Wu Yue Chun Qiu and so on. Among the top ten swords, some are real, and some are just the products of legend or literary rendering.

The ancient 10 sword in China is clearly recorded in history. Whether they really appear or not depends on archaeological evidence. It is said that Mo Xie was discovered in the Tang Dynasty, and Guo Zhen once presented this sword to Wu Zetian, but now there is no real thing. Long Yuanjian is still here, and the real thing is in the National Palace Museum in Taipei.

Extended data

In contemporary China, we can also see the shadow of the fallen iron sword. As early as 2003, the then Longquan sword maker made the first fallen iron sword in contemporary China.

There are many cold weapon collectors who have a special liking for meteorite swords, but the number of cold weapon players is relatively rare because of the high price and few works. Nickel-rich ferrites in meteorites are arranged in an angular staggered manner, and there is no through seam, so swords and various articles forged with them are stronger, more corrosion-resistant and sharper than ordinary swords.
