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

The purpose of this study is to scientifically analyze physicochemical characteristics the roof tiles used for palaces in Joseon Dynasty which stored Changdeokgung material storage and Seooreung Jaesil modern handmade ones made by N company understand differences between their manufacturing techniques. Through chromaticity, cross-sectional observation, component analysis, crystal structure it was possible confirm properties fired tile. Roof from have a wider colorimetric range higher apparent porosity water absorption, on average, than tiles. cross section shows that most clay minerals not been vitrified, remaining form atypical particles, while denser materials. X-ray diffraction analysis identified low-temperature such as micas but no peak these observed tiles, implying are at temperature ones. Therefore, density due use pugmills. general content main ingredients similar two. Additionally, principal trace elements showed samples were areas. It seems manufactured using soils supplied specific region same timeframe consistency components implies they also mix proportions clay.
