Abstract
ABSTRACT In this study, a Tara thangka (from a complete set of 21) dating to the mid-Qing Dynasty (1776–1839 CE) at Daxingshan Temple in Xi'an, Shaanxi, China was analyzed using various techniques, including portable X-ray fluorescence spectroscopy (p-XRF), Raman spectroscopy (RS), Fourier transform infrared spectroscopy (FTIR), optical microscopy (OM), and mass spectrometry-based proteomics. Through a multi-analytical methodology, in situ non-invasive testing was complemented with an analysis of a limited number of samples. By complementary evidence derived from the above analyses, it can be determined that the thangka was painted on a hemp substrate, with common colorants such as cinnabar, orpiment, gold, azurite, and malachite, and porcine glue as binding material. These results provided important scientific data for the production crafts of the precious Tara thangkas, contributing to the revelation of its value in art history and enabling conservators to make informed conservation decisions.
期刊介绍:
Studies in Conservation is the premier international peer-reviewed journal for the conservation of historic and artistic works. The intended readership includes the conservation professional in the broadest sense of the term: practising conservators of all types of object, conservation, heritage and museum scientists, collection or conservation managers, teachers and students of conservation, and academic researchers in the subject areas of arts, archaeology, the built heritage, materials history, art technological research and material culture.
Studies in Conservation publishes original work on a range of subjects including, but not limited to, examination methods for works of art, new research in the analysis of artistic materials, mechanisms of deterioration, advances in conservation practice, novel methods of treatment, conservation issues in display and storage, preventive conservation, issues of collection care, conservation history and ethics, and the history of materials and technological processes. Scientific content is not necessary, and the editors encourage the submission of practical articles, review papers, position papers on best practice and the philosophy and ethics of collecting and preservation, to help maintain the traditional balance of the journal. Whatever the subject matter, accounts of routine procedures are not accepted, except where these lead to results that are sufficiently novel and/or significant to be of general interest.
