“…It also proved its value in the study and conservation of two water‐saturated wooden objects from a 17th‐century shipwreck 4 . XRF has aided in improving the understanding of historical changes in human‐environment interactions related to obsidian procurement in central Japan during the Upper Paleolithic and provided insights into the pigment used in painted reliefs of fourth‐century BC Etruscan tombs 5,6 . XRD, SEM–EDS, and FT‐IR were effectively utilized together to study uncommon copper alloy artifacts dating back to the eighth‐century BC and their complex degradation phenomena to develop strategies for long‐term conservation 7 .…”

Analysis of Coronado State Historic Site artifacts using X‐rays

et al. 2023

Two historic‐period metal artifacts were provided by the New Mexico Historic Sites to Los Alamos National Laboratory for non‐destructive analysis. The artifacts were a crossbow quarrel (or bolthead) and a reliquary pendant recovered from Kuaua Pueblo (also known as the Coronado Historic Site) in Bernalillo, NM. The quarrel is a heavily patinated metal that had been flattened due to compressive forces. The pendant consisted of a metal casing that had previously surrounded two center gemstones on the front and rear face of the pendant. The gemstone in the rear setting had fractured and was displaced from the setting, leaving only a small, loose fragment within the pendant for study. The front gem appeared to be very dark, near‐black in color, and the fragment of the rear gem was a bright red color. The artifacts were analyzed to ascertain their composition and glean insight into their provenance using the following X‐ray techniques: X‐ray computed tomography, confocal micro X‐ray fluorescence, and X‐ray diffraction. Infrared spectroscopy and electron microscopy were used on selected areas. Ultraviolet Raman spectra were collected on the two gems and the pendant. The metal material of the artifacts was found to be primarily composed of copper. The gems in the pendant were composed of manganese (front gem) and calcium (side gem).
