This study uses type: variety-mode classification, digital stereomicroscopy, and Neutron Activation Analysis (NAA) to characterize the paste composition of Late Middle Preclassic-period pottery at the site of Holtun, Guatemala. The sample consists of 98 sherds including unslipped utilitarian ware, slipped serving ware, and Mars Orange fine paste serving ware. NAA reveals four paste composition groups that approximate types produced through type: variety-mode classification and paste groups recognized by digital stereomicroscopy. The analysis suggests a pattern of production in which unslipped utilitarian vessels, slipped serving vessels, and Mars Orange fine paste serving vessels were produced using different paste recipes. While unslipped utilitarian vessels and slipped serving vessels may have been produced and consumed locally, Mars Orange fine paste serving vessels were likely produced in or around Holtun but consumed more widely. Results of this research suggest the Late Middle Preclassic-period ceramic economy at Holtun was characterized by incipient specialized production, and exchange of at least one ceramic ware. These results advance our understanding of Late Middle Preclassic-period ceramic production and exchange at Holtun, and inform the study of the development of socio-political complexity in the Maya lowlands. 2 Archaeological Background Geographically, the Maya lowlands encompass the department of Peten Guatemala, Belize, eastern Mexico including parts of the states of Chiapas, Tabasco, Campeche, Quintana Roo, and Yucatan; and a portion of western Honduras (the state of Copan). Chronologically, the Middle Preclassic period spans approximately 700 years from 1000-300 BCE, with sites seeing occupation most frequently during the Late Middle Preclassic (600-300 BCE). It is during this time that multiple forms of settlements appear in the lowlands ranging from communities like Cuello (Hammond 1999), K'axob
