Specimens are fabricated by using a traditional Japanese metal craft technique. An aqueous solution containing cupric sulfate, alum and artificial verdigris is used to color the alloy sheets. Coloring is performed at 373 K ( °) 100 C . The fine structures are observed using a transmission electron microscope. The matrix of the colored layer consists of crystalline and amorphous Cu ～ { }//  { } O and the crystal size is 30 80 nm. The relation Cu O 111 Cu Au 111 is observed between the grown Cu O and the 2 2 2 matrix Cu  Au alloy. The Au fine parti
