■ Description A. Introduction This is a rare Late Koryo Dynasty Celadon Tea Bowl (approx. 14th Century). It is a fascinating transitional piece that retains the beautiful olive-green glaze of classic Koryo Celadon while featuring the silica spur marks that indicate the stacking techniques of the era.

B. Expert Analysis: Dating the Piece (Late Koryo vs. Joseon)

• The Silica Spur Marks (Keiseki): Inside the bowl (Mikomi), there are three distinct white marks. These are from quartz/silica stones used to stack bowls in the kiln. The use of high-quality silica supports (rather than rough sand) strongly points to the Late Koryo period, preserving the dynasty's high standards even as mass production began.

• Glaze Color: The glaze is not the gray or white-slip style of the later Joseon Buncheong ware. Instead, it maintains the transparent, olive-green celadon hue characteristic of the Koryo tradition.

C. Features

• Form: A shallow, open shape (Hirajawan), ideal for summer tea or serving side dishes.

• Texture: A mesmerizing network of fine crackles (Kannyu) covers the surface.

• Foot: The clay at the foot is relatively refined, consistent with Koryo wares.

D. Size & Weight

• Diameter: 14.0 cm / 5.51 in

• Height: 3.4 cm / 1.33 in

• Weight: 136 g / 0.30 lbs

E. Condition Condition: Antique

• Kiln Effects: The spur marks and glaze crackles are intentional or natural features of its age.

F. Conclusion A genuine piece of history from the 14th century. This bowl captures the final, rustic evolution of the glorious Koryo Celadon tradition. The silica marks inside are a highlight for any collector of Korean ceramics or Tea Ceremony utensils.
