Raman microprobe analysis of stucco samples from the buildings of Maya classic Copan
Goodall, Rosemary A., Hall, Jay, Edwards, Howell G. M., Sharer, Robert, Viel, Rene, & Fredericks, Peter M. (2007) Raman microprobe analysis of stucco samples from the buildings of Maya classic Copan. Journal of Archaeological Science, 34(4), pp. 666-673.
Micro-Raman spectroscopy has been applied to painted stucco samples from three buildings at the Maya site of Copan, Honduras. The buildings, Clavel (AD 450-550), Ani (AD550-650) and Temple 22 (AD730,) date from three phases of the Classic Period (AD400-820) acropolis construction. The red pigment has been identified as hematite and the stucco as a mixture of calcite particles dispersed throughout a calcite based lime wash stucco. The physical structure of the stucco changed through time indicating a refining of production techniques over this period. By combining Micro-Raman spectroscopy with other micro-ATR infrared spectroscopy and environmental scanning electron microscopy a detailed investigation of the materials and production techniques used to decorate these buildings has been made. Differences in the mineralogy of the red pigment used on each building indicate a different geological pigment source for each period.
