Iberian storage jars, also called Spanish olive jars, are one of the most widely occurring Spanish ceramic to be found in the New World having been used by the French and English as well as the Spanish. These vessels were used to transport, wine, olive oil, olives and fish. Generally, Iberian storage jars were either globular with a round or pointed bottom. Iberian storage jars have been recovered in New England from Pemaquid, Maine in an 18th century context and from the circa 1628 to 1676 Plymouth Colony trading house at Cushnoc in Augusta, Maine.
One fragment of an Iberian oil jar was recovered from the cellar hole. Another was found in a posthole associated with the addition added to the north side of the house in the 18th century.
