The sgraffito pottery is a red earthenware, coated with a white slip through which designs have been incised. An amber lead glaze imparts a golden yellow to the slip-covered portions and a brownish amber to the exposed red paste. The gravel-tempered ware is made of a similar red-burning clay and is remarkable for its lack of refinement, for the pebbly texture caused by protruding bits of gravel, and for the crude and careless manner in which the heavy amber glaze was applied to interior surfaces. Once seen, it is instantly recognizable and entirely distinct from other known types of English or continental pottery. A complete oven (fig. 10), now restored at Jamestown, is of similar paste and quality of temper. It has a roughly oval beehive shape with a trapezoidal framed opening in which a pottery door fits snugly.

(_Sketch by Mrs. Constance Christian, from photo._)] Following the initial discoveries at Jamestown there was considerable speculation about these two types. Worth Bailey, then museum technician at Jamestown, was the first to recognize the source of the sgraffito ware as "Devonshire."[1] Henry Chandlee Forman, asserting that such ware was "undoubtedly made in England," felt that it "derives its inspiration from Majolica ware ... especially that of the early Renaissance period from Faenza."[2] Bailey also noted that the oven and the gravel-tempered utensils were made of identical clay and temper. However, in an attempt to prove that earthenware was produced locally, he assumed, perhaps because of their crudeness, that the utensils were made at Jamestown. This led him to conjecture that the oven, having similar ceramic qualities, was also a local product. He felt in support of this that it was doubtful "so fragile an object could have survived a perilous sea voyage."[3] Since these opinions were expressed, much further archeological work in colonial sites has revealed widespread distribution of the two types. Bailey himself noted that a pottery oven is intact and in place in the John Bowne House in Flushing, Long Island. A fragment of another pottery oven recently has been identified among the artifacts excavated by Sidney Strickland from the site of the John Howland House, near Plymouth, Massachusetts; and gravel-tempered utensil sherds have occurred in many sites. The sgraffito ware has been unearthed in Virginia, Maryland, and Massachusetts.
