Investigation of smalt in cross-sections of 17th century paintings using elemental mapping by laser ablation ICP-MS

Next to highlighting the microanalytical potential of laser ablation-ICP-MS for multi-elemental mapping (on trace, minor and major element levels simultaneously) of smalt in paint cross-sections, this work will elaborate (statistical) data processing protocols for elucidation of cobalt ore provenance, possible deterioration mechanisms and the conservation state of the three examined paintings.
