Jar with Tall, Perforated Stand, 5th century, Unknown Korean, 23 3/8 x 12 3/8 in. (59.37 x 31.43 cm), Earthenware with natural ash deposits, Korea, 5th century, In the early 300s, Korean potters began constructing multichambered kilns in hillsides. These 'climbing kilns,' as they are now known, were capable of reaching temperatures around 2,200˚F, which yielded highly durable stoneware. One of the most commonly produced ceramic forms was a pedestal decorated with pierced, geometric patterns and surmounted with a bowl or jar. Discovered during excavations of tombs and palaces, these vessels are believed to have been used both for utilitarian and ceremonial purposes.
