Scientific Comparison Study on the Joseon Dynasty Palace Roof Tiles and Modern Handmade Roof Tiles

Modern roof tiles differ significantly from Joseon Dynasty palace roof tiles in firing temperature, density, and structural properties. Analysis of chromaticity, cross-sectional structure, component composition, and crystal structure revealed that Joseon-era tiles exhibit higher porosity, greater water absorption, and a wider color range, with unvitrified clay minerals and low-temperature mineral peaks like micas. In contrast, modern handmade tiles show denser clay materials and no such mineral peaks, indicating higher firing temperatures. Principal component analysis of trace elements in Joseon tiles suggests consistent sourcing from specific regions during their manufacture, implying standardized clay mix proportions. This study provides critical insights into the manufacturing techniques and technological evolution of roof tiles over centuries.
