This is a Celadon Prunus Vase from the Goryeo Period. It is 43.0cm high with a 6.3cm wide mouth and 15.3cm wide base. This piece of art has the typical style of the mid Goryeo Period. It has a relatively large mouth in a photospheric shape, and its expanded shoulder line curves smoothly to the bottom forming singularity in the structure. The glaze is a pale green semi-transparent color with thin icy lines. The design on the top of the lid is simple. The lateral surface design is divided into three areas with inlaid lotus flower leaves in a simple form. The simple yet concise application of inlaid design on four parts of the body is remarkable. This prunus vase is very unique among existing pieces, because it has both the lid and the body. Eight out of the nine celadon prunus vase that are national treasures use inlaid techniques. This prunus vase's unique shape imposes a refined style of the early 12th century, and stands out among others.
