The glass data set studied by Lemberge et al. (2000) consists of 180 different 16-17th century archeological glass samples. Electron Probe X-ray Microanalysis (EPXMA) intensities across \(750\) energy levels are recorded using a Jeol JSM 6300 scanning electron microscope equipped with an energy-dispersive Si(Li) X-ray detection system (SEM-EDX).
