ELEMENTAL ANALYSIS OF ANCIENT CHINESE INK STICKS BY PIXE
Abstract
Four ancient Chinese ink sticks were analyzed by PIXE. One sample is estimated to belong to the Ming Dynasty period(1368–1644). Three others including a red one belong to the Ching Dynasty period(1646–1912). Trace elements such as Si, P, S, Cl, K, Ca, Ti, Cr, Mn, Fe, Ni, Cu, Zn, As, Br, Sr, Pb were detected from black Chinese ink sticks. From red one, Si, S, Cl, Ca. Cr, Fe, Cu, Sr, Mo, Ba, Hg, Pb were detected. These trace elements show the materials or making processes of those sticks and every specimen has its own characteristics. At the same time, some pieces of Japanese paper and those stained with Chinese ink had been analyzed. These results show that the characteristics of ink upon paper can be determined by PIXE.
