35 years ago, the discovery of No. 1 and No. 2 sacrificial pits in Sanxingdui made the ancient Shu civilization wake up and startle the world.
Today, Sanxingdui site released the latest archaeological excavation results, lifting the mystery of ancient Shu civilization again! What are the cultural relics of Sanxingdui kingdom? Can the new discovery solve the existing mystery?
In a new round of excavation in the Sanxingdui sacrificial area, the expert team of China Silk Museum found the remains of decayed silk, and silk protein was repeatedly found in soil samples, proving that the Sanxingdui civilization has begun to use silk. Experts reveal how to discover the silk in Sanxingdui: the color of the soil with silk fabric residue must be different.
Sichuan has a humid climate. Fragile silk can't be kept for more than 3000 years in the humid underground. How can we find it? Archaeology over the years also shows that no silk more than 3000 years ago has ever been found in Sichuan before. The discovery of silk seems to be a distant problem.
Before silk identification, it mainly depended on the appearance. Human textile fabric fibers mainly include cotton, wool, hemp and silk. When you zoom in, its cross-section is different. But after thousands of years, some of the silk buried in the ground are very fragile, some even decay directly, and the appearance is difficult to preserve and identify. Through the self-developed enzyme-linked immunosorbent assay (ELISA) technology, China Silk Museum has greatly improved its recognition ability by using immunological technology to detect silk fabric residues.
