Abstract

To clarify the detailed features of the red bengala samples excavated from the Shimo-ohgibaru archaeological site in the late Yayoi period (2<sup>nd</sup> to 3<sup>rd</sup> century A.D.) from the viewpoint of materials science, colorimetric measurements, X-ray fluorescence analyses, X-ray diffraction measurements, transmission electron microscope observations, and surface area measurements of the ancient bengala samples were achieved. The ancient bengala sample was found to be high purity <i>α</i> - Fe<sub>2</sub>O<sub>3</sub>. The features of the color tone and particle size of the ancient bengala were clarified by comparing with those of commercially available bengala, Fukiya bengala, and synthesized <i>α</i>-Fe<sub>2</sub>O<sub>3</sub>. In addition, the starting materials and synthesis processes of the ancient bengala were discussed by applying the elutriation experiments of representative natural hematite and heat-treated natural iron hydroxide (Oniita).
