청자 양각죽절문 병 - A blue and white vase sitting on a table

Goryeo ware is a type of Korean ceramic pottery that was produced during the Goryeo dynasty, which lasted from 918 to 1392. The pottery was known for its exquisite beauty and high quality, and it was highly prized by collectors and connoisseurs throughout East Asia. Goryeo ware was produced in a variety of styles, including celadon, white porcelain, and black-glazed pottery. The most famous and highly prized of these styles is celadon, which was made using a special technique that involved applying a glaze containing small amounts of iron oxide to the surface of the pottery before firing it in a kiln. The resulting celadon pottery had a distinctive pale green color, with intricate designs and patterns etched into the surface. Goryeo celadon was highly valued for its delicate beauty and its ability to withstand the test of time. Today, Goryeo ware is considered one of the greatest achievements of Korean ceramics, and examples of it can be found in museums and collections around the world.
