Abstract
ABSTRACT The adoption of pottery in the Upper Great Lakes region occurs quite late compared to the greater Eastern Woodlands. Recent organic residue analyses suggest that the earliest pottery in the Upper Great Lakes region was likely used to process acorns. Through experimental means using temperature as a proxy, this paper evaluates the efficacy of leaching tannins from acorns by comparing two regionally available cooking technologies: stone boiling versus simmering in a ceramic vessel. Our results indicate that tannins can be more effectively leached at simmering temperatures like those provided by ceramic vessels. At boiling temperatures, tannins are irreversibly bound to the acorn starches, rendering the nutmeat inedible in further processing. While there are a number of reasons to adopt and use pottery, it appears that processing acorns may be another important addition to this growing list.
期刊介绍：
Ethnoarchaeology, a cross-cultural peer-reviewed journal, focuses on the present position, impact of, and future prospects of ethnoarchaeological and experimental studies approaches to anthropological research. The primary goal of this journal is to provide practitioners with an intellectual platform to showcase and appraise current research and theoretical and methodological directions for the 21st century. Although there has been an exponential increase in ethnoarchaeological and experimental research in the past thirty years, there is little that unifies or defines our subdiscipline. Ethnoarchaeology addresses this need, exploring what distinguishes ethnoarchaeological and experimental approaches, what methods connect practitioners, and what unique suite of research attributes we contribute to the better understanding of the human condition. In addition to research articles, the journal publishes book and other media reviews, periodic theme issues, and position statements by noted scholars.
