This flattened globular jar is decorated with incised circles and bands of diamond-shaped patterns on the shoulder. It has a tiered lid with lotus bud knob and is covered in brown glaze. This jar may have been used as an oil lamp or simply for oil storage.Khmer ceramics are glazed with two main types of glaze; one is a thin pale green, translucent and finely crazed while the other varies from mottled chestnut brown to black. Both glazes were also used to decorate a single vessel.Excavations have shown the earliest glazed wares were introduced by the end of the ninth century but gradually diminished after abundant product in the 12th century. By the 14th century, they seem to have disappeared altogether. Khmer pottery was produced mainly for local use rather than as export wares. However, pieces have been retrieved from Cambodia and former Khmer-influenced regions including Thailand, Vietnam, Laos, and the Malay peninsula.
