Since January 15, the process of opening and preserving the inner sarcophagus of the man believed to be the Marquis of Haihun commenced in a hermetically sealed laboratory one kilometer west of the dig site in Guanxi, Jiangxi Province, where the Han Dynasty tomb was discovered. Off-limits to media and the public, the excavation process involved state-of-the-art preservation technology aimed at protecting and cataloging some 10,000 artifacts in what some are terming a “conservation ER.”
Lab
The artifacts removed from the tomb include tapestries, embroidery, metal containers, lacquerware and other objects of cultural and artistic significance. Most pieces are too fragile to be cleaned on-site, and thus the focus of the conservation effort is gradually shifting to the nearby lab complex.
Covering a total area of some 4,000 square meters, the Guanxi lab includes five workstations. Particularly impressive is the anoxia workstation, which utilizes aerospace technology to remove oxygen from the atmosphere and suspend vulnerable artifacts in an almostpure bubble of nitrogen with climate control technology allowing humidity to be adjusted to between 20 and 80 percent. Conservationists, armed with oxygen masks, work in a 20-square-meter glass tank pre-fitted with hermetically sealed containers for the most fragile relics, including human remains.
At another workstation, broken pieces of lacquerware still bearing black and red markings are soaked in water and kept in individual“crispers” designed to prevent their brittle outer layers from completely disintegrating. But their preservation is not guaranteed. “We are not sure yet if all these fragments can be restored and reassembled according to their original appearances,” conservationist Guan Li told our reporter.
Lacquerware is notoriously vulnerable to environmental damage, and the Guanxi pieces spent millennia submerged in an underground midden, which preserved them but could not prevent them from beginning to crumble immediately upon contact with the air. Consequently, sterile deionized water is used to keep each piece of lacquerware soaked, with restoration work focused on reinforcement, careful removal, cleaning and dechromatizing, with conservationists using infrared scanning to reveal otherwise-invisible motifs and patterns. Each piece is then dehydrated and sealed in Plexiglas for long-term preservation.
