A green-glazed pot from the Han Dynasty (202BC-220AD). In the Han Dynasty, authentic celadon appeared for the first time in the history of Chinese ceramics, as well as ash-glazed pottery, colored gray pottery, black pottery, and lead-glazed pottery. The bronze ware culture that prospered from the Yin Zhou period to the Spring and Autumn Warring States period changed completely to the Han dynasty, when the technological innovation of celadon production occurred, and ceramics with various techniques and forms began to be made.
The green glaze of this item has a slight silvery appearance, giving it a subdued green color. It is said that this natural silver takes several hundred years or more. I put water on it for an hour and it didn't leak.
