What is a kind of cultural relic that disappeared in an instant unearthed from Mawangdui Han Tomb?

When archaeologists excavate cultural relics, what they fear most is the instantaneous oxidation of cultural relics when they see the light of day. This kind of thing has actually happened, and more than once. I remember the Terracotta Warriors first appeared in 1974. Archaeologists heard that several real pottery figurines were found in Xiyang Village, Lishan Mountain, Lintong, and quickly rushed to the scene to investigate. When the terracotta warriors and horses were first unearthed, they actually had colors, such as scarlet, dark green, pink purple and so on. However, as soon as the Terracotta Warriors came into contact with oxygen, their colors quickly faded in just 15 seconds.

Archaeologists used cameras to capture the Terracotta Warriors and Horses in a short time before they faded, and let us see the freshly baked Terracotta Warriors and Horses, but other Terracotta Warriors and Horses still became? Shame? The way it looks. Archaeologists have not yet mastered the technology that can not only unearth the terracotta warriors and horses, but also prevent the oxidation reaction, so they have not continued to excavate other tombs of the terracotta warriors and horses.

Along with the Terracotta Warriors, there is Mawangdui Tomb, which is located in Changsha City, Hunan Province. It was originally the family cemetery of Li Cang, the prime minister of Changsha in the Western Han Dynasty and Hou Jie. Archaeological excavations started at 1972 and were carried out three times in two years. More than 3,000 cultural relics were unearthed in Mawangdui, among which two national treasures, Mrs. Xin Zhui and Mrs. Xin Zhui, were both incorruptible female corpses.

According to archaeological research, Mrs Xin Zhui has 138 undigested melon seeds in her intestines. She died at the age of 50 because she ate too many melons at a time, which led to gallstones and finally caused coronary heart disease. And Mrs. Xin Zhui didn't rot after more than two thousand years, because she was buried deep underground and had a thick coffin seal.

When Mrs. Xin Zhui was excavated, the blood vessels in her hands could still be clearly seen, and some joints could still move. However, her plain gauze dress is only 49 grams, as heavy as an egg. The ancients were able to make such clothes, which shows that their silk weaving technology has reached a very developed level. Later, the Hunan Provincial Museum asked a research institute to copy this dress, and it took the research institute 13 years to copy it. Although it is imitation, the institute only copied 80 grams of plain gauze clothes, which is less than 1000 years ago.

Fortunately, Mrs Xin Zhui's body and plain gauze clothes were preserved. Now we can go to the Hunan Provincial Museum to see the real thing, but we can only see the following things in the form of photos, and we can only see photos for the same reason as the Terracotta Warriors.

There is some grain in Mawangdui Xin Zhui's tomb. Because wheat and barley are dry things, they turn black when exposed to oxygen, while fruits such as melons and fruits, bayberry and jujube react quickly when exposed to oxygen, and they haven't had time to take pictures.

Fortunately, there is a bowl of lotus root soup in the soil, which contains a lacquer ware. An archaeologist named Wang found this lacquerware, opened the lid and smelled a sour smell 2000 years ago. But this bowl of lotus root soup is not turbid at all, but it is still very clear. He was about to give this bowl of soup to his colleagues outside the tomb. He saw that lotus root soup was melting at an extremely fast speed. He called a photographer and the photographer took a picture before the lotus root soup melted.
