Description: English white salt-glazed stoneware, press-molded oval butter dish or butter tub (cover missing) decorated around the sides with panels of trellis diaper patterns of stars alternating with dots separated by basketwork and scrollwork in low relief. Butter dishes were manufactured in white salt-glazed stoneware in several shapes and sizes. Mountford shows similarly-shaped dishes with oval covers topped with a seated cow. Although Staffordshire white stoneware had been perfected by about 1720, its possibilities for mass-production were not fully exploited until the 1740s. Then the techniques of press-moulding, slip-casting and enamelling were developed, and the drabness of the greyish stoneware surface was successfully relieved by the addition of all-over decoration. The glaze on the stoneware was the result of throwing salt into a high temperature oven (1000-1100 degrees), where the heat caused the salt to volatilise and the soda in the salt to combine with the alumina and silica in the clay to form a thin vitreous glass-coating over the surface. That outer layer has characteristic minute pitting. Since there are no factory markings, it is very difficult to link pot with potter.
