One notable category in the collection is Buncheongsagi (grayish-blue powdered celadon), a type of celadon that was popular in the late 13th and early 14th centuries. During this period, political power shifted from the wealthy aristocracy to young scholars. These frugal scholars preferred ceramics with minimal decoration and a rough texture, reflecting their identity and their aspiration to replace material wealth with a new focus on scholarship.

The word Buncheong refers to the technique of covering blue celadon with white clay. This aesthetic aligns with the new elite's values, which emphasized breaking away from traditional social structures and embracing a freer, more casual style. The patterns on Buncheongsagi are relatively simple yet convey a sense of seamless expansion toward the future. Plants and animals are depicted with just a few brushstrokes or carvings, and even the multiple concentric circle brush marks around a rounded bottle create a stylish and dynamic design.

Buncheongsagi represents the hope for a new era and dynasty—a sentiment that resonates deeply with people across generations, as the desire for a better world is timeless.
