Book excerpt: Displaying, storing, and handling objects of cultural value is ideally accompanied by scientific analysis, which is almost never performed due to the limited analytical resources of most cultural institutions. If testing is feasible, stakeholders favour nondestructive techniques based on both ethical considerations and limited sampling availability. Coloured historical textiles are specially challenging because the best analytical method to date -high performance liquid chromatography (HPLC)- is destructive. Interested in developing an assessment tool that would provide comparable results to those achieved using HPLC, we built into ongoing research on 18th and 19th c. textiles from Norwich, UK. The application of statistically unsupervised multivariate classification methods on these textile's reflectance spectra showed that groupings were related to specific dye combinations, which were subsequently validated with HPLC. Successful preliminary blind-tests on other samples of similar provenance, showed promise in developing a methodology that can non-destructively assess other materials, using predictive models that use pre-validated reflectance datasets.
