Abstract

The mineralogy of the glazed surfaces of Japanese sekishu roof tiles covered by a crustose lichen – Lecidella asema (Nyl.) Knoph & Hertel – was investigated using transmission electron microscopy (TEM). The study sought to identify the Ti-Fe mineral observed as a low concentration of Ti and Fe in a previous study of the glazed surfaces of the same roof tile. The TEM analysis revealed that: (1) a thin layer of the Ti-Fe mineral pseudobrookite exists on the glaze surface; (2) the pseudobrookite consists of well-ordered single crystals, continuously and widely distributed on the glaze surface.
