Figure 51 Jar or jug fragments, Benjamin DuVal Pottery, Richmond, Virginia, 1811–1820. Salt-glazed stoneware. (Photo, Gavin Ashworth.) These incised fragments were the most enigmatic artifacts found during the DuVal salvage recovery. They suggest very high quality incised decoration previously unassociated with the DuVal operation or, for that matter, any Richmond-area stoneware.
