Sixty‐one ceramic samples collected in Cuenca, Ecuador, were analysed by neutron activation analysis in an attempt to establish their elemental compositions. The bulk of the samples were manufactured in the region of Cuenca, with others imported from Quito in the northern highlands of Ecuador, from Panama Vieja in Panama, and from Seville in Spain. Relative to the Cuenca ceramics, the Spanish samples were separable primarily by their high Ca contents; the Panamanian ceramics by their high Cs contents; and the Quito ceramics by their high Na contents. The ceramics made within the region surrounding Cuenca are much more difficult to separate, with Ba and other elements being potentially important.
