Description: Jade. China, Late Neolithic period, early Bronze age, c. 2000 BC
This large bi disc has such a strongly weathered surface that the jade looks almost disfigured and appears completely coated by a white patina. It looks almost as if the surface is covered with snow, from which emerge fragments of the texture of the jade. Compared to its diameter, the disc is very thin, with a central small hole which has been drilled from both sides. These features suggest a date around the early Bronze age period
A similar large disc measuring 26.3 cm but with a larger hole (9 cm) and a strongly weathered surface is part of the collections of the National Museum of History, Taipei. Dated to the Shang period, it is published in Jade: A Traditional Chinese Symbol of Nobility and Character /玉:中國傅統美的象徵, National Museum of History, Taipei 1988 (text in English and Chinese), p.26.
