Abstract:
The corroded surfaces of historical glass samples were studied by micro‐Raman spectroscopy. The spectra acquired from lateral and stratified mapping were analyzed by principal component analysis providing the number of linearly independent spectral components and by multivariate curve analysis resulting in spectrum of native glass and spectra of different corrosion products (loadings) and their relative abundances (scores) in each measured spot. The obtained results were qualified by comparison of results obtained by stratified mapping with the results of lateral mapping. On the basis of dominant scores, the lateral distribution of various corrosion products was identified. The quality of corrosion products was only roughly identified by the spectral database (S.T. Japan spectral database).
