概要	Use-wear analysis (also called microwear or tool-use analysis) is a method that infers the function of stone tools from microscopic wear patterns on their cutting edges and surfaces. Pioneered by Lawrence Keeley in the 1970s-1980s, this technique examines damage patterns, polishes, and edge rounding produced as tools contact different materials during use. By analyzing these wear patterns, archaeologists can determine whether a tool was used to cut plant material, meat, bone, hide, or wood—revealing detailed information about task specialization and subsistence practices in prehistoric societies.	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.
