Yu Geun-Hyeong

Yu Geun-Hyeong (유근형 ; 柳根瀅), pen name Haegang, (April 5, 1894 – January 20, 1993) was a Korean ceramist and played the leading role in the revival of Goryeo celadon.

In 1913 the firm opened an outlet within the Tokyo's business district Nihonbashi which likely sold Yu's earliest works.

Gisaku had established Sanwa Goryeo Celadon Ware[8] in 1908 in the town of Nampo in South P'yong'an Province (now North Korea).

[9] Members of the Yi Royal Family, that had been absorbed into the Imperial House of Japan, controlled many of the shares of Gisaku's firm.

[4] Yu's experiments with kiln designs, and different clays are said to have played an essential role in advancing the production of quality Goryeo style wares.

Noritaka reportedly surveyed 700 sites of old kilns, recovered and classified an enormous quantity of ceramic artifacts.

He was honored by the government as a Living National Treasure as holder of Intangible Cultural Property No.13 of Gyeonggi Province.

[15][16] His work is held in public collections, including The Asian Art Museum of San Francisco (object number 1992.232) and The British Museum (object number 1992,0623.1-2) During his many decades Yu produced a great number of ceramic works including: Video showing Yu at work: Koryo Celadon,1979 - YouTube Smithsonian Museum ceramic dish signed by Kwang-yeol Yoo showing two extra dots in signature
