Mountains in the north provided the necessary raw materials such as firewood, kaolinite, and silicon dioxide for the master potters while a well established system of distribution transported pottery throughout Korea and facilitated export to China and Japan.

An additional six kilns remain in Sudongni which date to the 14th century but most have been destroyed due to river erosion and farming.

These celadon kilns were still employing techniques from previous centuries although the colors, patterns, and glazes used were very diverse.

Excavations unearthed a wide variety of pottery fragments diverse in shape, size and colors.

The Goryeo Celadon Office was established in 1986 to preserve kiln sites and also to reproduce and reconstruct the techniques lost many hundreds of years ago.
