Buncheong ware was evolved from Goryeo celadon, created with the same kind of clay and glaze. The distinctive style of Buncheong came from the use of white slip on top of the grayish clay used for celadon. This method allows ceramists to use the decorative techniques that were refined by Goryeo ceramists, such as the inlay technique, with more freedom and experimentation. Dumbeong Buncheong is one of the late styles of Buncheong ware. Dumbeong refers to the dipping technique of applying slip to the entire vessel by holding its bottom, and soaking it upside-down in the slip.

Park Sungwook is known for using the Dumbeong Buncheong technique. He maintains the classic ethos of Korean bowls and jars, with the experimental touch of Buncheong. One can appreciate how the white slip flows on the gray clay underneath the lower part of the utensils. The way the surface cracks in the kiln offers a more dramatic effect than white porcelain. He continues to experiment and innovate using this old technique of ceramic making.
