Colonial panel paintings constitute an essential part of Latin-American cultural heritage. Their study is vital for understanding the manufacturing process, including its evolution in history, as well authorship, dating and other information significant to art history conservation purposes. Raman spectroscopy supplies a non-destructive characterization tool, which can be implemented situ analysis, via portable equipment. Specific methodologies must developed, comprising elaboration reference...
Abstract In pre‐Hispanic Mesoamerica, pigments and dyes were used in the elaboration of a large variety colored objects. Obtaining information regarding objects' material composition is useful restoration preservation processes, as well for recovering knowledge its production technology context history object. Yellow colors have been obtained from Mexican natural resources. Although mineral yellow pigments, such orpiment oxides, are relatively easy to identify by nondestructive noninvasive...
Abstract Almost three hundred Spanish colonial missions—or their remains—are scattered over the vast state of Chihuahua in northern Mexico. A few them still display painted decorations on wood ceilings and walls. The decorated areas vary greatly, from whole ceiling main aisle to just a square meters lateral chapel, so does conservation paintings. In this context, information regarding paintings’ composition plays key role restoration processes. For gathering such information, we propose...
Raman spectroscopy is often used for non‐destructive analysis of works art, polymers and biological materials, but in some cases, the laser beam can cause damages on surface being studied due to deposited energy. When possible, such damage be prevented by minimizing intensity or acquisition time, this usually available only high sensitivity bench‐top spectrometers. Portable spectrometers are commonly not so flexible an alternative needed ensure safe study sensitive art other fragile...
Despite being one of the largest complexes at Teotihuacan, Plaza de las Columnas has been least studied. Recent archaeological discoveries by Project Complex revealed that its inhabitants maintained an evident relationship with Mayan area. The methodology employed consisted first a surface examination materials via imaging techniques. Afterward, mineralogical characterization was achieved Infrared (FTIR) and Raman spectroscopies, X-ray diffraction (XRD) for complementary analysis, while...
