Dye analysis can considerably enhance our understanding of the provenance of materials used in the production of historical objects. Knowledge of the individual constituents of any dyestuff not only facilitates its identification, but also provides important information regarding the rate of photo-degradation of the dye’s components; this can in turn support decisions regarding conservation and display. This Technical Brief outlines the principal analytical methods used in dye and mordant analysis, by explaining how to select the most appropriate experimental conditions and describing the types of instrumentation available.
