The representative pottery type of Gojoseon is Misongri-type pottery. It was first discovered at a cave in Misong-ri in Uiju, Pyonganbukdo Province, hence the name. Vessels have a flat base, a rounded body, a pronounced mouth that spreads outwards, and band-shaped handles. Mainly discovered in stone coffin burials, its distribution extends from the Liaoning and Jilin regions to the north of the Cheongcheon River. Around the same time in the northwest regions of the Korean Peninsula south of the Cheongcheon River, top-shaped pottery was used instead.
