STON: SofTware for petrOgraphic visualisatioN

What is STON and why did we do it?
Thin-section petrography is a widely used technique in archaeology for analyzing the composition of ceramic and stone objects, as well as investigating their production technology and provenance (Reedy, 2008; Peterson & Betancourt, 2009; Quinn, 2022). This method involves studying these materials in thin sections mounted on glass slides under a polarizing microscope to examine their microscopic features. A critical aspect of archaeological study is the comparison and identification of patterns within these features across multiple samples. However, it is typically only possible to view one sample at a time under the microscope. As a result, this method relies heavily on visual memory and repeated observations, making the process inefficient and time-consuming, particularly when dealing with hundreds of samples.
This tool is designed to address these challenges by enabling users to observe multiple photomicrographs simultaneously within a single, convenient interface. It facilitates detailed comparisons, clustering, and data recording, which is especially important in ceramic paste analysis. By allowing users to view multiple samples side by side, the software supports efficient sample grouping and evaluation of compositional characteristics.
While tailored for the specific requirements of petrographic analysis in archaeology, the software has broader applications in other research fields that rely on visual image analysis. By providing an efficient and scalable tool for comparative analysis, it enhances research processes across various disciplines.
