A combination of micro‐Raman spectroscopy, micro‐infrared spectroscopy and SEM–EDX was employed to characterize decorative pigments on Classic Maya ceramics from Copán, Honduras. Variation in red paint mixtures correlated with changing ceramic types improvements process firing techniques. We have confirmed the use specular hematite Coner by difference intensities Raman bands. Different compositions brown were imported local wares. The carbon‐iron composition type, Surlo Brown, confirmed. By...
Abstract Micro‐Raman spectroscopy was applied to the study of multiple layered wall paints from Rosalila temple, Copan, Honduras, which dates Middle Classic period ( A.D. 520 655). Samples red, green and grey paint a thick white overcoating were analysed. The pigments have been identified as hematite, celadonite or earth combined carbon/mica mixture. By combining Raman with micro‐ATR infrared environmental scanning electron microscopy (ESEM), detailed has made materials processes used make...
Fourier transform infrared (FT-IR) attenuated total reflection (ATR) imaging has been successfully used to identify individual mineral components of ancient Maya paint. The high spatial resolution a micro FT-IR-ATR system in combination with focal plane array detector allowed particles the paint be resolved and identified from their spectra. This micro-Raman spectroscopy characterize paint, which was found mixture hematite silicate minor amounts calcite, carbon, magnetite sub-micrometer...
A large medical sea chest was investigated to identify the composition of various medicines contained within. During investigation, complex history also revealed, from its likely use on migrant ships travelling England Australia later rural properties in Victoria and New South Wales. Infrared spectroscopy (ATR-FTIR) X-ray fluorescence (pXRF) were used combination investigate 21 chest, confirm labelled contents unknown substances mixed medicines. Synchrotron micro-infrared analysis as well...
Sealable polyethylene bags are widely used to protect and store heritage items. While is regarded as a stable material, consideration should be given potential chemical interactions between the polymer stored objects. The presence of additives in manufactured storage materials also considered when they contact with For this study, infrared spectroscopy has been successfully identify associated additives, well characterise changes that undergo. Three case studies presented demonstrate can...
Mercury is present in the Museums Victoria collections a variety of forms. These include mercuric chloride applied as pesticide, pigments and paints containing mercury sulfide, scientific equipment liquid geoscience specimens including native cinnabar. All these materials can release vapour into storage cabinets have potential to contaminate both surfaces other nearby specimens. Extensive testing identified higher than acceptable levels inside cabinets. Air from was sampled across all...
For the past six years conservation and collection management departments at Museums Victoria have been conducting a major survey to determine type extent of hazardous substances in collections better inform safe handling storage practices. This paper focuses on mercury compounds collection, including chloride applied as pesticide, sulfide pigments, liquid used scientific equipment, mineral specimens such native cinnabar. All these can release volatile vapour into furniture potential...
