Colorants used in Japanese woodblock printing are sometimes derived from natural sources. While more vibrant when produced, these colorants often fade with time due to their chemical properties and sensitivities to light, moisture and other environmental exposure factors. In our work with the Portland Art Museum, we aim to develop a methodology that will allow for the identification of colorants (or classes of colorants) through analysis of specific molecular vibrations.
