Analysis of lead isotopic ratios of glass objects with the aim of comparing them for forensic purposes

► Pb-isotope ratios were analysed for glass samples. ► We examined their evidential value from a forensic chemist's perspective. ► We applied a likelihood ratio test and Empirical Cross Entropy in order to analyse its performance. ► It was found that 208Pb/204Pb seems to be a promising variable for solving a comparison problem.
