This study discusses the investigation of a series of pit-kilns in and around the prehispanic site of Kiuic in the Puuc region of the northern Maya lowlands and presents the multiple lines of evidence that identify these structures as lime production features. The study reports the results of systematic excavations, archaeometric analyses, archaeological experiments, ethnographic inquiries, and spatial analyses. Burnt lime has been used for architectural, dietary, hygienic, and other purposes by the Maya for at least three millennia and yet its importance in prehispanic Maya society is belied by the lack of lime production features identified in the archaeological record. The identification of these structures as lime production features has implications for understanding subregional differences in socioeconomic organization and resource management practices among the prehispanic Maya. This report provides a model for using multiple methods and analyses to investigate and identify lime production kilns that can be applied to societies and landscapes throughout the Maya area and the broader premodern world.
