Retrieving Tarnished Daguerreotype Content Using X-ray Fluorescence Imaging—Recent Observations on the Effect of Chemical and Electrochemical Cleaning Methods
We report a study on the effect of chemical and electrochemical cleaning of tarnished daguerreotypes observed using X-ray fluorescence (XRF) microscopy with a micro-focussed X-ray beam from a synchrotron source. It has been found that, while both techniques result in some success depending on the condition of the plate and the experimental parameters (chemical concentration, voltage, current, etc.) the effect varies, and cleaning is often incompl…
Bromine, a possible marine diet indicator? A hypothesis revisited
This study examines the hypothesis that bromine in human skeletal tissue serves as an indicator of marine diet. Synchrotron‐based X‐ray fluorescence microscopy of samples from archaeological sites on the Peruvian North Coast showed relative enrichment of bromine in the cementum and osteons. X‐ray absorption spectroscopy determined organobromine to be present, suggesting an exclusive association with the organic component. We used skeletal tissue …
Recovering Past Reflections
The first commercially viable photographic image, the daguerreotype, captured images for a span of approximately 20 years (1839–1860). DeDterioration now disfigures many of these valuable images. One proposed restoration method is an electrochemical process. However, its safety and effectiveness are still under debate within the conservation community as the effects of this treatment, and its physical and chemical impact on the daguerreotype imag…
Changes in the Metal Content of Human Hair During Diagenesis From 500 Years, Exposure to Glacial and Aqueous Environments
Scanning electron microscopy, inductively coupled plasma mass spectroscopy and time‐of‐flight secondary ion mass spectrometry have been used to examine the extent and possible mechanisms by which the metal content of human hair is altered by exposure to aqueous environments. The results, using both modern hair and samples from 500‐year‐old hair associated with glacier‐entombed remains, show that the metal content has been altered sufficiently so …
