Neutron activation analysis (NAA) of Coarse Orange jars demonstrates economic exchange among the Classic period political capitals of Totocapan, Matacapan, and Teotepec in the Tuxtla Mountains of southern Veracruz, Mexico. Matacapan, in particular, displays evidence of intensive pottery production at large workshops at the southern margin of the site. Comoapan (Area 411) and Area 199 present configurations of kilns, ceramic densities, and assemblage characteristics that suggest production for exchange beyond the site's boundaries. Both of these production facilities specialized in the production of Coarse Orange jars, a well-made and decorated utilitarian ceramic ware. While these products were traded to sites in the Tepango Valley, different paste recipes of the Coarse Orange type were also produced locally. Of broader concern, I examine the articulation of these regional exchange relationships with the interregional interactions previously documented among Tuxtlas groups and others in central Mexico and the Gulf Coast.
