A key site for discussing the rise exchange networks centering on craft products is the site of Kulaksizlar, situated in Turkey. It is of special interest because there is evidence for the production of marble vessels. The marble raw material for these stone vessels and other rocks used in the manufacturing process, such as grabbo, basalt, and sandstone, were located within walking distance of this place. The most common artefacts were pointed beakers. 

The beakers are conical in shape and have two vertical lugs with piercings near the rim. The manufacturing required a considerable input of labour and amount of skill. Production stages of beakers include coarse flaking, pecking, drilling and polishing. There are numerous stages in the production during which the stone could brea, for example due to a structural weakness in the marble used, this resulted in a large number of rejects found at the site. 

The remarkable thing thing about these beakers is that they have features that make them difficult to produce in stone, they have have perforated vertical lugs and protruding heads set on a narrow fragile neck. Given that these characteristics made the beakers more difficult to produce, it is possible that this added to the perception of craft products made with skilled labour- whereas a pointed beaker without lugs would have represented a large labour investement and less skill.
