The spotted-pattern porcelain is shaped through the method of molding clays with 3-odd colors and then baked after putting glaze on it.

Porcelains of this type showing a natural harmony of colors in effect of color pattern were made only in some regions between the late 11th century and the mid-12th century, and few of them are conveyed.

Yu Kwan Jun, a creator of the North Hamgyong Provincial Fine Arts Studio, succeeded in making spotted-pattern porcelain in Juche 96 (2007) and further developed its know-how, that was listed as a national intangible cultural heritage in 2018.

In this regard, Yu told KCNA:

The spotted-pattern porcelains in the past were usually 7-10 centimeters high, but I made them nearly ten times bigger in size than old ones to retain the modern aesthetic taste while inheriting the old technique.

Typical of them created by Yu is a 60 centimeter-high vase presented to the 2nd National Sculpture and Craftwork Festival held in September last to celebrate the 73rd DPRK birthday. Eight of the spotted-pattern porcelains produced by him were registered as the national treasures.

Yu and his family, including his two sons, are now devoting their wisdom and passion to the creation of spotted-pattern porcelains out of the mind to further glorify the precious assets of the nation.
