The white porcelain jar is usually wide with a height over 40 cm . It is also

called the "Moon jar", which is reminiscent of a full moon with a milk-white

 hue.

During the first century of the late 18th through the early 19th century,

It is presumed to be manufactured in the official kilns(Gwangju,Kyeonggi-do)

Bunwon.

Because of its sheer size, it was hard to put it up on the spinning wheel so that it

 was made by throwing the top and bottom sections separately and joining them

 at the center to complete the molding and firing, which seemed to be a very

difficult work.

The beauty and balance of pure white is a unique and representative form of

white porcelain, unprecedented in the world.

The curve of the body line is round and very glamorous.

With a soft curve, rounding about the shoulder, narrowing steadily without any

defect until arriving at the bottom, almost in a perfect circle. It is typical style of

 white porcelain in mid-Chosun Dynasty, the appearance and curve of wide

mouth opening and the narrow lower areas make it voluminous and stable,

 providing a sense of harmony and balance.

The whole surface of the porcelain is evenly arranged without any marks, which

shows that it is produced

in the highest level of environment and is close to the curved vertical and tidily

edged.

Its height is 50.7 cm, diameter of body 47.2 cm, diameter of mouth 24.5 cm, and

diameter of bottom 17.8 cm.

The shape of the body is round and voluminous. It doesn’t have any defect in

the combined middle part, so the curve is a nearly perfect circle.

The glaze is transparent without any colors, which appears to see through the

white color of the clay as it is, and has a subtle pin-hole on the front side and a

good melting status. The clay used is selected, its density is slightly lower, and

celadon is pure white or slightly pale blue.
