☆Sagijang refers to a person who has the ability to bake a china bowl at a high temperature of more than 1,300°C by mixing various soil.
The late Kim Yun-tae, who was the owner of Sagi-jang, was a man of Mungyeong. Mungyeong was widely distributed with red clay, white clay, sajil clay, and pottery, and the water in the valley was good, so around 1700, when artisans who had crossed over Mungyeongsaejae Hill settled down and mainly produced tea cups and semi-phase machines. The Galjeonyo of Mungyeong was a kiln run by Kim Yun-tae's grandfather, and was succeeded by Kim Jong-seong, Kim's uncle, although there was a few years of absence from the post-liberation period until the Korean War.
The production of traditional Korean ceramics can be largely divided into the divisional atomizer operated by the government and the privately owned porcelain that originated naturally in various parts of the country during the late Joseon Dynasty. Among them, the private sector can be divided into areas where skilled sagijangs were kidnapped by Japan during the Japanese Invasion of Korea in 1592, and Kim Yun-tae inherited a kiln tradition in northern Gyeongsangbuk-do, a representative mountain area for civilian prisoners who escaped kidnapping.
Kim Yun-tae inherited the kiln from his grandfather Kim Il-bae and uncle Kim Jong-seong during the late Joseon Dynasty and produced pottery for the rest of his life. Among the fields of household porcelain and bowls were excellent.
They have the characteristics of a local kiln at the end of the Joseon Dynasty and inherit traditional techniques. In addition, the entire process of collecting clay, receiving water, making bowls, cutting, chiseling, and grilling are following the traditional production style of the late Joseon Dynasty.
Kim Yun-tae was in charge of the entire process of white porcelain production, including digging clay, pulling out the dough and air bubbles, making a lump of clay to be placed on a spinning wheel, wiping out the holes in the molded bowl, and applying glaze, as well as the role of the underwater forces in all the white porcelain production.
Kim Yun-tae did all of this, especially the traditional kiln production technology made of mangdeng (or mangsaeng) was considered the best in Korea, as few people were able to do the entire process of white porcelain production alone across the country.
Kim Yeong-gil, the eldest son of Kim Yun-tae, was recognized as the owner of sagijang in March 2015 for his ability to carry out not only his father's traditional techniques but also his family's construction of kilns and spinning wheels using Mangsaeng, and to handle the entire process of making traditional white porcelain by himself.
