The Restoration of the Largest Archaelogical Discovery—a Chemical Problem: Conservation of the Polychromy of the Chinese Terracotta Army in Lintong

The conservation of the polychromy of the terracotta army of the first Chinese emperor Qin Shihuangdi represents a special problem because of the deterioration of the ground layer consisting of organic material. This was triggered due to it having spent more than 2200 years in water-saturated soil. The consolidation of the polychromy was achieved through polymerisation of a specially adapted combination of monomers.
