Although Cheongsong white porcelain is not included in the magnetic and pottery facilities of King Sejong’s treatise on geography, it is assumed that it was produced from the 16th Century and has been continuously produced until the 20th Century. With a long history of about 500 years, Cheongsong white porcelain is of great historical significance to the extent that it has been consistently mentioned by local ceramic historians and Japanese potteries, although there was a time when history records were temporarily cut off with the closing of the last Cheongsong Sagi workshop. The geographical environment of Cheongsong area and the unique materials of Cheongsong White Porcelain has led to the establishment of the production facilities and production process of Cheeongsong Sagi Workshop. As grinding process was required due to the nature of the raw materials, the workshops secured competitiveness by simplifying and improving the molding and firing methods in order to save time and money required. After continuous efforts and research by the members of Cheongsong Sagi Workshop, Cheongsong Sagi took about 10 hours to complete with single firing. In modern times, the Cheongsong area has attracted public attention along with Yanggu area as a production site for white porcelain materials, as a large quantity of high-quality white porcelain clay macs were discovered. The discovery of white porcelain clay mac is significant in materialistic aspects and it is hoped that further experimental studies will be conducted to contribute to the development of domestic raw materials.
