The 1992 publication of Pottery Function brought together the ethnographic study of the Kalinga and developed a method and theory for how pottery was actually used. Since then, there have been considerable advances in understanding how pottery was actually used, particularly in the area of residue analysis, abrasion, and sooting/carbonization. At the 20th anniversary of the book, it is time to assess what has been done and learned. One of the concerns of those working in pottery analysis is that they are unsure how to “do” use-alteration analysis on their collection. Another common concern is understanding intended pottery function—the connections between technical choices and function. This book is designed to answer these questions using case studies from the author and his colleagues for applying use-alteration analysis to infer actual pottery function. The focus of Understanding Pottery Function is on how practicing archaeologists can infer function from their ceramic collection.
