Non-destructive characterization of decorated porcelain artifacts requires the joint use of surface-analytical methods for the decorative surface pattern and methods of high penetration depth for bulk-representative chemical composition. In this research, we used position-sensitive X-ray Fluorescence Spectrometry (XRF) and Prompt-gamma activation analysis (PGAA) for these purposes, assisted by 3D structured-light optical scanning and dual-energy X-ray radiography. The proper combination of the near-surface and bulk element composition data can shed light on raw material use and manufacturing technology of ceramics.

对装饰瓷器文物进行无损表征需要联合使用针对装饰表面图案的表面分析方法和针对具有代表性的整体化学成分的高穿透深度方法。在本研究中，我们为此目的使用了位置敏感型X射线荧光光谱法（XRF）和瞬发伽马活化分析（PGAA），并辅以三维结构光光学扫描和双能X射线成像。近表面和整体元素组成数据的恰当结合能够揭示陶瓷的原材料使用情况和制造技术。
