ミズノコイワ カラ ハッケン サレタ ビゼンヤキ

The sintering process of a broken piece of Bizen-yaki vase discovered in Mizunoko-iwa and its components were studied by means of X-ray diffraction and electron microscopy. The components of the sample discovered in Mizunoko-iwa were mainly mullite, cristobalite, quartz and feldspar. Quartz and feldspar were much contained in it, compared with Bizen-yaki of recent days. It is considered that the sintering process was similar to the process now in current. As a result of electron microscopy, the needle-shaped and thin crystal were observed in the sample above mentioned. The formation of needle-shaped crystal was considered to be due to the reaction with the sea water. The Bizen-yaki vases in Mizunoko-iwa were generally porous and raw materials were comparatively rough

This paper presents an associative restoration system that creates the restoed shape of a given distorted ancient pottery in terms of its plane figure (silhouette). The system has been implemented on the VAX11/780 computer system, based on a mathematical modeling of the associatve memory and additional processing techniques. One of the aims is to reduce archaeologists\u27 labor spent in drawing a huge number of plane figures corresponding to finds given by excaticns. In our computer simulation, we use 14 types of silhouttes of the "Sueki", Japanese ancient potteries, as the test figures. The results of the simulation are presented and also are discussed in relation to the system performance and archaeology
