An abacus-shaped salt jar baked in Hoeryong or Myongchon in North Hamgyong Province in the latter half of the Joseon Dynasty. Unlike the salt jars of South Korea, this piece’s base is not squeezed, and the appearance of sitting on a flat bottom is impressive. Initially, it seems that the aim was to bake black, but two-thirds of the whole is greenish brown, and it is unexpectedly two-tone.

In the Hoeryong region, it is customary to put the vessel on an open flame, and the bottom is also slightly carbonized. There are no other noticeable defects.
