A blue and white cup fired in the middle of the Joseon dynasty. It shares characteristics with the underglaze iron works of local kilns at the same period, such as the flowy drawn grass pattern and the flat base. However, due to financial constraints during that era, the importation of cobalt was challenging, resulting in the use of iron oxide for decorative materials. Consequently, the application of cobalt in white porcelain was unusual in the mid Joseon period. Beyond its captivating design with ink black colour that invites contemplation, this rare sake cup has a favourable size.

There are no noticeable defects other than kiln scratches, and the condition is excellent. It comes accompanied by a box.
