Numbered Jun ware are rare, early 15th-century ceramics that are famous for their beautiful blue and purple variegated glazes; they were used in the private quarters of the Forbidden City, the Chinese imperial palace in Beijing. In this talk, conservator Susan Costello discusses the chemical origins of these unique glazes and how she worked to restore the striking glazes on a damaged ceramic during a conservation treatment.
This research was carried out in conjunction with the 2017 exhibition Adorning the Inner Court: Jun Ware for the Chinese Palace, curated by Melissa A. Moy, then the Alan J. Dworsky Associate Curator of Chinese Art at the Harvard Art Museums. To learn more, visit our Numbered Jun Ware digital resource, which introduces this remarkable ceramic ware and explores its many complexities.
This video is part of our Art Talks series, in which our team of curators, conservators, fellows, and graduate students will share short, informal videos that offer an up-close look at works from our collections.
