The Challenge: Preserving History Amidst Degradation
Ancient glass artifacts undergo significant compositional changes due to long-term burial weathering, compromising chemical analysis and classification. Traditional methods often fail to account for the complex, nonlinear nature of these alterations, leading to inaccurate interpretations of historical technology and trade.
Our Solution: A Multi-Model ML Framework
We propose a comprehensive machine learning framework leveraging Ridge Regression, XGBoost Regression, and Multilayer Perceptrons (MLP) for pre-weathering composition reconstruction, complemented by an XGBoost classifier for glass type identification. SHAP analysis provides critical interpretability.
Key Impact: Enhanced Archaeological Insight
This framework significantly improves the accuracy of ancient glass analysis, enabling reliable identification of original recipes and technological systems. It provides archaeologists with a robust tool to overcome weathering challenges, leading to more precise historical reconstructions and improved conservation strategies.
- Up to 20% error reduction in composition reconstruction.
- 98.7% accuracy in glass type identification.
- Data-driven insights into weathering mechanisms and key elemental roles.

Case Study: Unveiling Ancient Chinese Glass Secrets
By applying the framework to excavated ancient Chinese glass, we successfully reconstructed original compositions for highly weathered samples. This revealed distinct production recipes (potash vs. lead-barium) with 98.7% accuracy, significantly enhancing our understanding of ancient glass technology and trade routes despite severe degradation. SHAP analysis confirmed that PbO and K2O are critical indicators for both weathering and classification.
