| Research Abstract |
The raw materials of the lead-glass and lead-glazed ceramics were examined the difference about age and productive region. It paid attention to the two type of lead-glazed ceramics; (1)Excavated in the 7th century site, (2)Japanese tri-colored ware which appeared in the 8th century. These shards were analyzed to clarify the chemical haracteristics. Though the use of the lead raw material in two or more regions was admitted in the 7th century, the existence of glaze using a domestic lead raw material was clarified in Asukaike site. So it was confirmed that domestic production had been done in the latter half of the 7th century. Moreover, the shards that existed besides the area where the lead isotope had been called 'concentrated area of the Nara era' up to now was newly found from the Japanese lead-glaze among the 8th century shards. In addition, the green pigment that was the raw material of the green glaze was able to clarify existence by at least two types.
