■ Description A. Introduction This is a rare Late Koryo Dynasty Celadon Tea Bowl (approx. 14th Century).

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.
