| Research Abstract |
Broze implements are classified into three groups: (1)implements made in China and brought to Japan,(2)implements in Japan originally, (3)imitations of the Chinese ones made in Japan. These Chinese implements are distinguished from the copied japanese ones by comparison of shapes, ornamental patterns and skillfulness of manufacturing technique. The chemical compositions of the mirrors are also one of the effective measures to distinguish them.
A distinction between Chinese and Japanese implements seems to be possible, in a majority of cases, by determining the tin to lead ratios non-destructively without taking corrosion conditions of the surfaces into Oaccount. With this investigation into the relationship of chemical composition to surface analysis by X-ray spectrometry, there may be a possibilty of finding not only the porduct places but also the chronological sequence of implements by analyzing samples in any condition even corroded areas.
