Stone bowl fragments have been reworked into a variety of small pendants and plaques. There are also a number of artifact types that appear for the first time in the Batman Drainage at Demirköy. Of these, the most noteworthy are a number of objects made of plastic media, specifically bitumen and clay. The objects are sand tempered and represented by two types. The first is a small ring-like object represented by three fragmentary examples. All have a ring diameter of a few centimeters and a band diameter of a few milimeters. The second type is a small cigar-shaped, bead-like object a few centimeters long, represented by a single example.
