A Study of Change in Processes of Stone-ware (Sueki) Production from the Ancient Times to the Middle Ages in Japan -a Case Study Main in Kinki Region-

为了研究近畿地区从古代到中世纪的石器（末器）生产，最重要的是阐明丹波（京都县中部地区）的一组筱窑遗址。是平安时代著名的生产中心。因此，我们选择了志野遗址作为本研究的对象，推进了研究工作。由于大谷3号窑址是筱窑最大的转折点，因此我们首先将重点放在大谷3号窑址上，并对该窑址进行了多次发掘。我们的调查和发掘发现了两座窑址（分别称为大谷3-1和3-2）。大谷3-2窑生产普通的末器和高级的青釉瓷器，共到世纪末。而大谷3-2被证明是最古老的釉陶瓷生产的遗迹在志野。此外，我们确认大谷3-1窑是日本世纪末规模最大的窑。因此，这些结果确实为引发日本生产Sueki和上釉陶器的演变过程带来了宝贵的启示。通过此次调查，发掘出了良好的遗存，可以说，在志野窑北部地区，出土的陶瓷数量最多，内容最丰富，对平安时代的研究做出了贡献。除了考古调查外，我们还与自然科学各领域的专家进行了联合调查。联合调查包括陶泥地质调查、窑址考古地磁测量、陶瓷用陶泥化学成分分析、青釉器铅同位素分析、窑址木质材料鉴定等5项研究。在这两次调查中，我们获得了关于平安时代的信野窑和陶瓷生产的重要知识。

In order to research stoneware (Sueki) production in Kinki region from the ancient times to the Middle Ages, it is the most important to elucidate a group of kiln ruins of Shino in Tamba (middle area of Kyoto Pref.) which was eminent production center in Heian period. Therefore we chose Shino ruins in this study and pushed forward investigations. Above all, we assigned a focus to the Otani 3 kiln site and performed several excavations of that site, because the Ohtani 3 kiln site had been operated at the greatest turning point of Shino kilns.Our survey and excavation revealed two kilns (identified as Ohtani 3-1 and 3-2). Ohtani 3-2 kiln produced both common Sueki and high-ranked green-glazed ware, altogether by the end of the 9th century. And Ohtani 3-2 proved to be the oldest remains of glazed ceramic's production known among Shino. Furthermore, we confirmed that Ohtani 3-1 kiln is a maximum-scale kiln in the end of the 9th century Japan. These results therefore do bring a precious light on the evolution process that triggered the production of Sueki and glazed pottery in Japan. By this investigation, good remains are excavated, and we can assert that excavated ceramics contribute to the study of Heian era because they were the largest quantity and the most substantial contents in north area of Shino kilns.As well as archeological examinations, we performed joint investigations with experts of various fields of natural science. The joint investigations consisted of 5 researches ; geologic examination about potter's clay, the archaeological geomagnetism measurement of a kiln bedside, chemistry ingredient analysis of potter's clay used for ceramics, lead isotope analysis of green-glazed wares, identification of carbonized wooden materials used at kilns. In both investigations, we got important knowledge about Shino kilns and ceramics production in the Heian era.
