The North Devon potteries manufactured for export, sending their wares to Ireland as early as 1600 and to America by 1635. The trade was particularly heavy in the years following the Stuart Restoration and was tied to the influential 17th-century West-of-England commerce with America. New England, Maryland, and Virginia received many shipments of North Devon pottery, an entire cargo of it having been delivered in Boston in 1688. Sgraffito ware found in colonial sites in Virginia and Maryland is from a common source. The style of decoration is unique to English pottery and reflects Continental elements of design. It is reminiscent of decoration found on English and colonial New England furniture and embroideries. The only counterparts of this ware--matching it in style, paste color, and technique--are found among 17th-century sherds excavated from the sites of two potteries in Barnstaple. The 18th-century and 19th-century North Devon sgraffito ware surviving above ground differs considerably in style and form but in other respects it is the same as the ware found archeologically in Virginia and Maryland. The stylistic differences, noticeable on a piece in the Glaisher collection dated as early as 1704 (in which traces of the earlier style remain), were introduced by the turn of the century, thus strengthening the conclusion that the sgraffito tablewares found archeologically in this country must date from before 1700.
