Characterizing Song Dynasty ceramics using molecular biology fluorescence technology

We have used a new technology, fluorescent imaging, to examine Song Dynasty ceramics, renowned for their exquisite craftsmanship and unique crackle patterns. By capturing high-resolution images of microstructural features and crackle networks that are illuminated by specific wavelengths of light, we have been able to discern differences that seem to distinguish between products of the Northern and Southern Song dynasty periods; these can be further divided by the patterns into five major types of Ge-like ware. Fluorescence technology thus offers a relatively simple, inexpensive and non-invasive method for the characterization and study of ancient ceramic vessels. In addition, analysis of the emitted fluorescence provides insights into the composition and distribution of glaze materials that are not revealed by other methods, deepening our understanding of historical craftsmanship and technological innovation.
