Web Description: 
Beginning more than 4,000 years ago, disk-shaped bi made from jade were buried in graves with the deceased. When Chinese glassmakers became skilled in casting, they began to make bi from glass, often in colors that imitate natural stones such as jade. The spiral patterns on this example represent clouds.
