The collection of the Freer Gallery of Art, Smithsonian Institution, includes almost three hundred Korean ceramics spanning the Three Kingdoms, Unified Silla, Goryeo, and Joseon periods. This online catalogue presents all of those works and gives information about their dating, place of production, and provenance. The notable strengths of the collection are celadon wares of the Goryeo period (918–1392) and tea bowls made for the Japanese market in the Joseon period (1392–1910).
