The distribution of the artifacts found includes Finnmark (Norway) in the north, the Kalix River (Sweden) and the Gulf of Bothnia (Finland) in the west and the Vistula River (Poland) in the south. In the east the Comb Ceramic pottery of northern Eurasia extends beyond the Ural mountains to the Baraba steppe adjacent to the Altai-Sayan mountain range, merging with a continuum of similar ceramic styles. It would include the Narva culture of Estonia and the Sperrings culture in Finland, among others. They are thought to have been essentially hunter-gatherers, though e.g. the Narva culture in Estonia shows some evidence of agriculture. Some of this region was absorbed by the later Corded Ware horizon.
Comb Ceramic was not limited in Europe, being widely distributed in the Baltic, Finland, the Volga upstream flow, south Siberia, Lake Baikal, Mongolian Plateau, the Liaodong Peninsula and the Korean Peninsula. The oldest ones have been discovered from the remains of Liao civilization - Xinglongwa culture (6200 BC - 5400 BC).
The Pit–Comb Ware culture is one of the few exceptions to the rule that pottery and farming coexist in Europe. In the Near East farming appeared before pottery, then when farming spread into Europe from the Near East, pottery-making came with it. However, in Asia, where the oldest pottery has been found, pottery was made long before farming. It appears that the Comb Ceramic Culture reflects influences from Siberia and distant China.
The ceramics consist of large pots that are rounded or pointed below, with a capacity from 40 to 60 litres. The forms of the vessels remained unchanged but the decoration varied.
By dating according to the elevation of land, the ceramics have traditionally (Äyräpää 1930) been divided into the following periods: early (Ka I, c. 4200 BC – 3300 BC), typical (Ka II, c. 3300 BC – 2700 BC) and late Comb Ceramic (Ka III, c. 2800 BC – 2000 BC).
