Sperrings ceramics is the original name given for the younger early Comb ware (Ka I:2) found in Finland.

The settlements were located at sea shores or beside lakes and the economy was based on hunting, fishing and the gathering of plants.

The typical Comb Ceramic age shows an extensive use of objects made of flint and amber as grave offerings.

Finds suggest a fairly extensive exchange network: red slate originating from northern Scandinavia, asbestos from Lake Saimaa, green slate from Lake Onega, amber from the southern shores of the Baltic Sea and flint from the Valdai area in northwestern Russia.

The culture was characterised by small figurines of burnt clay and animal heads made of stone.

There are sources noting that the typical comb ceramic pottery had a sense of luxury and that its makers knew how to wear precious amber pendants.

The great westward dispersal of the Uralic languages is suggested to have happened long after the demise of the Comb Ceramic culture, perhaps in the 1st millennium BC.
