SUMMARY:Weds Talks:Understanding Pigment Composition in Kerala Temple Murals using non-invasive Imaging Techniques
DESCRIPTION:Speaker: Moupi MukhopadhyayPh.D. StudentUCLA Conservation of Material Culture IDPAbstract: The wall paintings in the Indian state of Kerala belonging to the Kerala mural tradition (7th – 17th century CE) provide important cross-cultural links that contextualize local historical religious practices\, trade\, and social interactions. The complex color scheme of the paintings is traditionally attributed to the skillful use of only five colors (panchavarna) – black\, red\, yellow\, green and white. However\, the available literature on the technical study of the murals does not consistently assign the same material (coloring agent or pigment) to the composition of a single color. For example\, while black is generally accepted as lamp black across different publications\, the green has been ascribed to green earth\, powdered leaves\, or combinations of yellow ochre\, gamboge\, indigo\, and even lapis lazuli. Understanding the materials used in specific temple murals\, and their possible sources\, can help better understand the nature and movements of the agents involved in the creation of these paintings. Advances in material characterization methods have significantly increased the scope of identifying the composition of the colors in murals non-invasively\, ideal for the preliminary research required to build a case for a more intensive technical study. Non-invasive fieldwork was conducted on selected temples in Kerala\, using a digital single-lens reflex camera (DSLR) for photography as well as Infrared (IR) imaging\, and a SPECIM IQ hyperspectral camera for hyperspectral imaging (HSI). Permissions to access the temples allowed for the use of only sunlight as the illumination source\, adding to the complexity of the interpretation of the data obtained. The use of Infrared False Color Imaging (IRFC) in conjunction with the analysis of HSI data reveals photophysical characteristics of the pigments which are useful for their identification\, and for determining optimal characterization methods for further scientific investigation.Bio: Moupi Mukhopadhyay is a PhD Candidate in the Conservation of Material Culture Program IDP at UCLA. She is interested in investigating the photophysical and chemical properties of pigments in cultural heritage materials using scientific techniques\, to better inform their conservation. Through her research\, she aims to develop a better understanding of the materials and technology of the creation of temple wall paintings in Kerala\, India.

SUMMARY:Weds Talks: Working with Collections from Crete and Central Africa: My Third Year Journey Thus Far
DESCRIPTION:Speaker:  Celine WachsmuthM.A. StudentUCLA/Getty Conservation of Archaeological and Ethnographic Materials MAAbstract: One of the requirements for the MA Conservation degree is a nine month (minimum) internship in one or more conservation labs. By the end of my internship year\, I will have worked in three different places; the Institute for Aegean Prehistory Study Center for East Crete (INSTAP)\, the AfricaMuseum\, and the Denver Art Museum (and a very exciting one month at the Denver Museum of Nature and Science). In this talk I will give a brief description of the different things I’ve been up to since starting my third year. This summer I spent six weeks in Crete working on archaeological ceramic\, metal\, and glass objects from various sites around East Crete. After a break in August to travel and see family\, I started my second internship in Belgium. Here I’ve shifted gears and been heavily involved in the installation process for a contemporary exhibition and treating a wood object going out on a loan. Bio: Céline is a third year student in the UCLA/Getty MA program in conservation. She has had the chance to work in many great conservation labs including at the Penn Museum\, the Cleveland Museum of Art\, a private objects lab in Seattle\, a private automaton and horological lab in Seattle\, the Anchorage Museum\, Fowler Museum\, INSTAP\, and now the AfricaMuseum.
