Relative Heating Effectiveness and the Decline of the Soapstone Cooking Vessel in Eastern North America
ABSTRACT During the North American Late Archaic Period, people produced ceramic vessels from clay and stone vessels from soapstone. While both ceramic and soapstone vessels proliferated across eastern North America, the former evolved and endured into the subsequent periods, while the latter declined. Here, we conducted an experiment to assess heating effectiveness between soapstone and ceramic vessels. We examined heating rate, ability to boil, heat retention, and thermal shock resistance. We predicted that if cooking performance contributed to the decline of soapstone vessels, then they would perform poorly relative to ceramic vessels. Our results did not support that hypothesis and revealed soapstone vessels were significantly more likely to reach a boil. We consider three other related factors: (1) sourcing and production costs; (2) subsistence change; and (3) exchange and mobility, which may have contributed to the decline of the soapstone cooking vessel and the continued investment in ceramic technology.
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.
