Excavations at the Celtic settlement of Sopron‐Krautacker (W. Hungary) make it possible to form an overall view on the local practice of pottery manufacture. Study of the soil conditions has established that the source of raw material is the nearly calcium carbonate‐free upper layer of the local soil resulting from a leaching process. By the various analytical methods used (XRD, XRF spectroscopy, and thermal analysis) composition of the pottery has been determined, and it has been shown that the vessels were fired at 600–7
