Abstract
Scientific analysis and testing of cultural relics are often carried out during the design phase prior to restoration, serving as the foundation for subsequent conservation treatment. Given the diversity and complexity of cultural relics, uncertainties are often present at all stages of conservation and restoration, making on-site analysis and testing at the conservation site highly significant for guiding protection and treatment. This paper, focusing on on-site conservation work for polychrome cliff carvings, discusses the application scenarios of several relatively simple and practical analysis and testing instruments—such as infrared thermal imagers, Leeb hardness testers, and spectrophotometers—at conservation and restoration sites.
