Buncheong Eggshell Flower Pattern Tea Bowl, Made by Seisho Mokujin The Buncheong eggshell flower pattern is a type of Buncheong ware made in the Joseon Dynasty. The delicate small flower pattern, like overlapping petals, is very beautiful. The skin tone, created by applying white slip to a grayish-blue base and firing it, has a simple and warm feel. This is a beautiful, unused tea bowl in good condition, so we hope someone who likes it will purchase it.
