"From mountains to molehills: a critical review of Teotihuacan's obsidian industry," in Economic aspects of prehispanic Highland Mexico, edited by Barry L. Isaac, Research in economic anthropology, supplement 2, pp. 23-74, JAI Press, Greenwich, CN. [437] notebook

Critical review of literature about obsidian mining, prismatic blade manufacture and related trade in Teotihuacan. Strongly suggests that the magnitude and economic importance of this activity has been exaggerated beyond what existing data will support. Good discussion of the technology of prismatic blade manufacture and how the remains of various stages of this process can be identified archaeologically.
