Recent excavations at The Long Bay Site uncovered artifacts of European manufacture intermingled with native Indian artifacts. These include seven very small glass beads (and fragments of three others), a coin, a small metal buckle, a D-ring, 32 sherds of melado ware, and two small sherds of white-glaze ware. Laboratory studies have been conducted to help determine the origins and dates of these artifacts. The glass beads are wire-wound and have an extremely unusual high-lead chemical composition. The coin is a billon blanca of Henry IV minted between 1471 and 1474. Both buckles were found to be lightly-leaded bronzes. The melado ware has a lead glaze, as do the white wares, although the latter also contain tin. All of the artifacts contain intentionally-added lead. Their isotope ratios spread over a range, but all are consistent with Spanish origins. The data indicate that the San Salvador artifacts were made in three locations within Spain.
