The purpose of this study was to identify the morphological characteristics and chemical properties of pipe-shaped iron oxide particles depending on the manufacturing method and provide information on possible manufacturing methods and locality survey of the excavated iron oxides. We collected samples around the Toratsuka Tomb and performed firing, followed by optical microscopy, scanning electron microscopy, X-ray fluorescence analyses, and X-ray diffraction analyses. Based on the results, it was demonstrated that the annealing temperature has no effect on the shape of the iron oxide samples while the particle size as well as the color and intensity ratio of iron oxide differed with the annealing temperature. We also obtained information on minor constituents of the iron oxide samples through elemental analyses and gained knowledge on determining the locality by identifying the contained elements.
