Green-glazed Oil Lamp, Qiong Ware

This lamp is very unique; the bowl-shaped oil lamp is hollow inside. Water was filled in the inner layer to cool off the heat of lamp, and therefore to decrease the volatilization of the oil. Tang dynasty saw the prosperity of the Qiong kiln in Sichuan province. Surviving ceramics datable to the Tang dynasty account for the largest part, including daily-used vessels, stationery, toys, and statues.
