Web Description: 
仿玉涡纹玻璃璧 Beginning more than 4,000 years ago, disk-shaped bi made from jade were buried in graves with the deceased to represent the status and power of the ruling class. When Chinese glassmakers became skilled in casting, they began to make bi from glass as a substitute material, often in colors that imitate natural stones such as jade. The spiral "涡纹" patterns on this example represent water.
