After lots of searching the web I found on a site by the Buffalo University more about Seyitömer Höyüğü, where these finds stem from. I found them extremely curious. The archaeological site of Seyitömer Höyük is located within the Kütahya region of western Turkey, 350 kilometers south of Istanbul, at an important juncture between the Mesopotamian and Mediterranean worlds. The development of advanced metal technology fuelled commerce between these distant regions as
early as 3,000 B.C., leading to the establishment of important trade centers linking east and west.
The best-preserved example of such a center is Seyitömer Höyük, where thousands of artifacts and dozens of pottery and textile workshops paint a vivid picture of village life from the Early Bronze Age through the Roman period. […] The archaeological site of Seyitömer Höyük is situated on top of a 12 million ton coal reserve. Beginning in 2015, a private company will extract this coal, and the archaeological site will be permanently destroyed. Students in this field school will have the opportunity excavate and document archaeological material from this threatened site, which will make a lasting contribution to archaeology. In addition, they will gain firsthand experience with the ethical issues surrounding cultural heritage management.

The notice in the museum came no further than "funnel terracotta".
