Tin-glazed wares occur in small numbers in Cape collections dating from 1630 to the 19th century. Tin-glazed wares constitute a minor part of all ceramic collections at the Cape, with the MNV count ranging from 11.7% in the Old Granary to 2.2% at Oudepost and a mere 1.3% in the Moat. Tin-glazed earthenware is a twice-fired, low-fired earthenware. Refined Industrial Earthenware in our collections includes refined glazed earthenwares made in Britain from the 1720s, as well as industrial wares that were mass produced in factories from the mid-18th century on. Jackfield is a red bodied black glazed refined earthenware, sometimes called ‘Black-ware,’ that was produced in England between 1745 and 1790. British refined wares began to appear regularly at Cape sites in the late 18th century, long after they became popular in Europe and North America.
