  • Title: Micro-attenuated total reflection spectral imaging in archaeology: application to Maya paint and plaster wall decorations.
    Author: Goodall RA, Hall J, Sharer RJ, Traxler L, Rintoul L, Fredericks PM.
    Journal: Appl Spectrosc; 2008 Jan; 62(1):10-6. PubMed ID: 18230201.
    Abstract:
    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 of a micro FT-IR-ATR system in combination with a focal plane array detector has allowed individual particles in the paint to be resolved and identified from their spectra. This system has been used in combination with micro-Raman spectroscopy to characterize the paint, which was found to be a mixture of hematite and silicate particles with minor amounts of calcite, carbon, and magnetite particles in a sub-micrometer hematite and calcite matrix. The underlying stucco was also investigated and found to be a combination of calcite with fine carbon particles, making a dark sub-ground for the paint.
