Some cases of chemical studies were carried out in finds of archaeology and works of art. I tried to research the possibility of the pottery color by graphical studies, used by digital photograph and Adobe Photoshop. Graphical studies were carried out on the five old Tokoname potteries, and three old Tanba potteries. These potteries were recorded by the digital photograph. The analyzed sample parts of the potteries were selected from 10 to 15 points on the natural glaze in the vase of photograph. The natural glazed color was studied by "a" cannel and "b" cannel from Lab color conversion of Photoshop. Based on the results obtained 8 samples were divided into three groups the 12th century's Tokoname, after the 13th century's Tanba and the 12th century's Tanba. But there were little difference among the three groups. So I had to study too few number of samples, and the sample of digital photograph were not shot by same condition. Now I have to get the method by Lab color conversion of Photoshop. I will study with the view of getting this method.
