This document summarizes research on characterizing the chemical composition and sociocultural identity of historical pottery from Pila, Laguna in the Philippines. The research aims to categorize chemical characterization as a dimension of pottery's sociocultural identity and characterize the Pila pottery. Samples were analyzed using Fourier transform infrared spectroscopy, x-ray fluorescence spectroscopy, and atomic absorption spectroscopy. The results found that the pottery samples contained silicon, aluminum, calcium, iron and other elements. This chemical characterization provides insights into the pottery's technology, durability, and helps deepen the understanding of its sociocultural identity. The research concludes that chemical characterization can be an additional dimension for analyzing the sources of pottery's socioc
