From the Middle copper age. From the Wikipedia: The Copper Age in the Middle East and the Caucasus begins in the late 5th millennium BC and lasts for about a millennium before it gives rise to the Early Bronze Age. Transition from the European Copper Age to Bronze Age Europe occurs about a millennium later, between the late 4th and the late 3rd millennia BC.

Pottery from Can Hasan I. Zigzag and hatched patterns in black of red paint on light coloured clay and white infilled lines on grey of buff backgrounds are characteristic of the Early Chalcolithic (Copper Age) pottery.

Mound I in Can Hasan (15 km northeast of Karaman) was inhabited between 6th-4th millennium BC. Most of the finds are exhibited in the Ankara Museum of Anatolian Civilisations.
