Inductively coupled plasma-atomic emission spectrometric determination of the concentrations of aluminium, barium, calcium, iron, magnesium, manganese, sodium, strontium, and titanium in 184 colourless container and sheet glasses was used to evaluate classification procedures for these two classes of glass. Effective two-dimensional visualiation of the classification results is afforded by principal components analysis of the data with correct classification of 180 of the 184 samples. Good discrimination among sources of glass within a class is provided using hierarchial, unsupervised clustering. Individual manufacturing plants of a common container glass can be distinguished in most instances.
