Black and red are foundational colors in Mesoamerican painting and scribal arts, often derived from easily accessible raw materials. Although their presence is ubiquitous, variations in chemistry and microscopic properties are data that tell a more nuanced story. This paper summarizes analysis of black and red colorants used in Maya wall paintings that contribute to observations regarding local traditions in manufacture, as well as individual variation in artistic practice. Reported results...
Collaborative Research on Maya Ceramic Vessels at LACMA (2017)
This paper features the Maya Vase Research Project, a collaboration of LACMA’s Conservation Center and the Art and the Ancient Americas Program, which is studying Classic-period Maya ceramics in the LACMA collection. The project’s first phase was to perform digital technical imaging, comprised of photography in different regions of the electromagnetic spectrum, starting in the visible and expanding from X-rays to the Infrared, including ultraviolet visible induced fluorescence. Digital rollout...
Fragments of Student Life: An Archaeometric Approach to Life on College Hill, Brown University, Providence, RI (2016)
Since 2012, Brown University has conducted annual excavations on College Hill with the aim of understanding diachronic changes in the campus’ physical environment and student activities. This poster presents the results of archaeometric research conducted on a variety of artifacts (ceramic, glass, and metal) excavated from a single context abutting Hope College dormitory (constructed 1822). The artifacts were analyzed using p-XRF, optical microscopy, SEM, and EDS, in order to understand their...
Immanence, configuration and the bloomery ironmaking process: identifying behavioural opportunities from physical constraints (2015)
All metallurgical systems conform to the scientific laws defined for chemical, physical and thermodynamic interactions. These laws place clear limitations on the range of technological possibility, but, more importantly, create technological opportunity. Some metallurgical opportunities will be better suited to particular socioeconomic and natural environments than others. Models derived jointly from Materials science and Geology on one hand and evolutionary sciences on the other can offer...
Results of Petrographic and NAA of Ramos and Babicora Polychromes from Across the Casas Grandes Region (2016)
Whereas past studies have suggested that some Casas Grandes polychrome types are more common in some geographic areas than others (see Brand 1935; De Atley 1980; Findlow and DeAtley 1982; Kelley et al. 1999; Larkin et al. 2004 for more complete discussions), these studies have been challenged as they assume polychromes recovered are made locally, rather than imported from other sites (Douglas 1995; Minnis 1984, 1989). As a result, recent studies refocus on polychrome production (Carpenter 2002,...
