Florence City Centre Historical Mortars: Digital Image Analysis of thin sections in view of conservation actions

Digital image analysis (DIA) of thin sections under polarized light microscopy emerges as a powerful tool for characterizing historical mortars, offering quantitative insights critical for conservation compatibility. This study analyzed three 14th–15th century bedding mortars from Florence’s UNESCO-listed historic center, revealing key compositional traits such as binder/aggregate ratios, porosity percentages, and granulometric selection. Findings highlight both the strengths and vulnerabilities of medieval construction techniques, providing a data-driven foundation for designing compatible repair materials. The approach bridges petrographic investigation with digital analysis, demonstrating its potential to inform long-term conservation strategies in heritage preservation.
