Figure 12  Jar, attributed to Jacob Foulk, Morgantown, West Virginia, ca. 1802– 1817. Earthenware. H. 8". (Private collection; photo, Gavin Ashworth.) This cylindrical string-tie storage jar shows trailed viscous dark slip and brushed white and green slip. The white slip is a de facto engobe, but the green slip appears to incorporate some white slip, as evidenced in the small leaflets.
