Deciphering the composition and microstructure of Jin-Yuan period oil-spot glazes from the archaeological site of Jining Lu of China.

ABSTRACT: This study investigates the structure-property relationship in Jin-Yuan period (1115-1368 CE) oil-spot glazes from the archaeological site of Jining Lu to elucidate the scientific principles governing their distinctive coloration patterns. Through multi-scale characterization of 20 ceramic fragments using ultra-depth microscopy, SEM-EDS (Scanning Electron Microscopy-Energy Dispersive Spectrometer), XRD (X-ray Diffraction), WDXRF (Wavelength-dispersive X-ray fluorescence) and XPS (X-ray photoelectron spectrometer) , we establish fundamental correlations between processing conditions, crystalline phases, and optical properties. The ceramic bodies exhibit a characteristic high-alumina composition (Al₂O₃: 24.5-34.0 wt%), reflecting regional clay sources and manufacturing
