Gilt-bronze Buddhist sculptures involve casting an image in bronze with a gold coating. Produced across Asia since the first century CE, these sculptures reveal production insights beyond stylistic studies. Research, including non-destructive techniques like X-ray fluorescence, enhances understanding of their craftsmanship. Two methods—piece-mold and lost-wax casting—dominate their creation, with ancient Buddhist sculptures featuring copper-tin-lead alloys. National Treasures No. 78 and 83, notable Korean examples, were crafted using lost-wax casting. Despite shared production methods, No. 83 exhibits better technical execution and fewer flaws than No. 78, showcasing advancements in casting techniques.
