Combined in situ micro-XRF, LIBS and SEM-EDS analysis of base metal and corrosion products for Islamic copper alloyed artefacts from Umm Qais museum, Jordan

Selected copper alloy artefacts from the collection of the Umm Qais museum at Irbid, Jordan, were studied by SEM-EDS analysis, while in situ analyses were performed by means of portable μ-XRF and LIBS spectrometers. Analysis and characterization of base metal and corrosion products of the copper alloyed artefacts were performed in relation to the environmental conditions of the display and as part of the overall assessment of the museum environment. Findings of this study are directed towards guiding a preventive conservation strategy for the copper alloyed artefacts at the Umm Qais museum.
