Abstract
The surface structure of a metallic mirror fabricated in the late Edo period has been investigated. A Sn layer of 100 nm thickness on the mirror surface is observed by cross-sectional Transmission electron microscopy (TEM). Hg is detected in the Sn layer by EDX analysis. This means that the surface Sn layer of the mirror was fabricated using an Hg-amalgam technique. By AES measurement, an Sn-Cu alloy at the interface between the Sn layer and the Cu base metal is detected. The Sn surface has been oxidized. The oxide layer consists of SnO2, SnO•SnO2, SnO and Sn in order of increasing distance from the surface.
