Abstract This paper exposes the results of Instrumental Neutron Activation Analysis (INAA) on 46 pottery sherds, fragments of Spanish olive jars (botijas) and stoneware containers (martabans) recovered from archaeological interventions in San Diego fort and Acapulco historic sector, a shipwreck site in the western coast of Baja California peninsula, and shipwrecks beneath of Gulf of Mexico and Caribbean Sea waves. The study was developed to obtain data on the geochemical-composition of pastes, lead-glaze and pitch coatings of the referred pottery sherds collection, with the aim of identifying the geochemical signature of each elementary composition of sherds. So, it was possible to propose a geochemical area of origin (manufacturing provenance) for the sampled ceramic vessels: according achieved results, many analyzed pottery sherds came from the Iberian peninsula, South America and Southeastern Asia, whilst other were locally-produced (namely the Acapulco Red Ware and Acapulco Glaze).
