概要	Instrumental neutron activation analysis (INAA) measures trace element concentrations in archaeological artifacts by bombarding samples with neutrons and analyzing the resulting gamma-ray emissions. Developed as a systematic archaeological method by Michael Glascock and colleagues, INAA provides chemical fingerprints of ceramics, obsidian, and other materials that reveal sourcing and provenance. The method is non-destructive, highly sensitive, and capable of detecting 30+ elements simultaneously.	Ceramic petrography analyzes pottery through microscopic examination of thin sections cut from pottery sherds. This method determines clay sources, identifies non-plastic inclusions (temper), and reconstructs pottery production technology. Pioneered by Peter Stimmung and others, ceramic petrography reveals whether pottery was made locally or imported, and whether specific production groups or workshops created vessels with distinctive raw material recipes.
