A Ceramic Compositional Perspective on the Formative to Classic Transition in Southern Mesoamerica

Abstract

We use neutron-activation analysis data on Formative- and Classic-period pottery along with analyses of modern ceramics and raw materials to examine changes in ceramic production and consumption on the central Guatemalan Pacific slope at the beginning of the Classic period. In particular, we wonder if the processes that generated regional distributions of two Formative-period wares (White Paste and Fine Red) were the same as or different from the processes that generated regional distribution of Classic-period Flesh ware. We identify probable production zones for the three regionally distributed wares based on raw-material analyses, consideration of the geological context of different zones, and distributional evidence. We find major differences between production/consumption of the Formative and Classic regionally distributed wares. This reinforces the notion that some kind of dramatic historical discontinuity affected the lives of Pacific-slope people around A. D. 200.
