This is a melon-shaped water ewer from the Goryeo period of the 11th century. The size is 14 cm in height to the lid and 20 cm in width. This color is also called celadon and was made with the aim of imitating jade. It dates from the peak of the Korean Goryeo period, from the 11th to the 12th century. It is rare to have a lid, making it a very valuable item. In the latter half of the 12th century, as the country gradually declined, the blue color became dull, and for some reason, inlay became more common, causing the value to drop significantly. There are slight traces of soil on the white marks of the foot, indicating that it is an excavated item, but it is in good condition. Also, the lines of the lid and the melon do not perfectly align, and the handle is slightly bent like this, which is proof of its authenticity from that time. I apologize for any potential return scams, but please note that this item is non-returnable.
