抄録

Powdered mineral pigments are used for The Tale of Genji picture scroll made in the twelfth century and the ancient Takamatsu burial mound made in the seventh century of Japanese. These pigments are chiefly composed of natural minerals in the world. For instance, the red color was hematite, and the blue color was lazurite (lapis lazuli). 12 kinds of pigments made in China that had been encountered recently were examined by X-ray diffractometry and visible spectrometry. As a result, the black was graphite with quartz, the white color was dolomite and aragonite, the blue color was azurite and turquoise, the green color was malachite, the red color was cinnabar and hematite, and the yellow color was orpiment. When the mineral grain size is less than 1 μm, the streak color is shown. Moreover, the color of pale blue was a color of the particle size of 1-8 μm, while blue pigments were the colors of the particle size of 25-65 μm of azurite. From these facts, in the case of azurite with a size of approximately 10-65 μm, the size of the mineral particle which constituted a color just presented a macroscopic color, but showed that a color became light when size became the fine grain of approximately 1-8 μm.
