a Micrograph of fiber collected from Ono no Komachi (32.75). b FTIR spectra of two areas of the fiber compared to relevant reference spectra. Dotted lines indicate peaks corresponding to a proteinaceous medium, such as animal hide glue (bottom), and the dashed lines indicate peaks likely arising from amylose-based rice paste (second from bottom). Hide Glue and Rice Paste spectra from the IRUG [42, 44, 45]
