An application of the X ray fluorescence and multivariate analysis for the study of the 18th century vessels from Lubaczow glasshouse

Full text: Provenance and dating problems constitute one of the most important challenges in the study of Baroque glass. The X ray fluorescence and multivariate analysis was applied for identification and dating of vessel glass originated from Polish glasshouse in Lubaczow. The 18th century Lubaczow glass from different periods was defined on the basis of differentiating the raw materials sources and the technology applied. The links between the stylistic featuring and chemical characterisation of glass vessels were found. A subset of variables that best discriminate between the groups were identified by application of the discriminant analysis method. The classification functions for allocating the new unclassified objects to the recognized groups were calculated. The obtained results show that the statistical tools are very useful and complementary to the stylistic studies of historical objects. (author)
