Large quantities of Longquan celadon were exported throughout East Asia, Southeast Asia and the Middle East in the 13th–15th century. Large celadon dishes were especially welcomed in Islamic nations. Since about 1420 the Counts of Katzenelnbogen have owned the oldest European import of celadon, reaching Europe indirectly via the Islamic world. This is a cup mounted in metal in Europe, and exhibited in Kassel in the Landesmuseum. After the development of blue and white porcelain in Jingdezhen ware in the early 14th century, celadon gradually went out of fashion in both Chinese and export markets, and after about 1500 both the quality and quantity of production was much reduced, though there were some antiquarian revivals of celadon glazes on Jingdezhen porcelain in later centuries.
