TL;DR: In this paper, a combined methodology for a fast, non-destructive and non-invasive characterization of paintings with a minimum of techniques was proposed, which includes false color infrared imaging as a first approach to determine the composition of large areas of the paintings and the homogeneity of the materials used in the painted areas, followed by small area analysis by X-ray fluorescence and fiber-optics reflectance spectroscopy.

TL;DR: Despite being one of the largest complexes at Teotihuacan, the Plaza de las Columnas has been the least studied archaeological site as mentioned in this paper, despite being the most popular tourist attraction.

TL;DR: A broader comparison with contemporary mural paintings from other Teotihuacan complexes shows good agreement in the materials used, which may suggest a standardization in the making of TeOTihuacan mural painting during the Xolapan period.

TL;DR: An interdisciplinary and multi-institutional group of science and art conservation specialists have provided new insight into the painting materials used in the polychrome walls and wooden ceilings as mentioned in this paper, and they provided new insights into the paintings used in polychrome wall and wooden ceiling.
