Figure 35 Mug, probably Scotland, ca. 1840. Pearlware. H. 4 1/8". Pearlware porter mug with several unusual features: the handle is press molded, as opposed to the normal extrusion; the interior is embellished with a painted, press-molded, life-sized frog; the thin brown slip bands near the rim and foot are decorated with white slip dots; and the exterior is trailed with four colors of slip, requiring a four-chambered slip pot. Most multiple, parallel trailed lines of slip found on dipped wares are a single color. To date, the only factory known to be associated with this type of decoration is that of John Thomson at the Annfield Pottery, Glasgow (1812–1884).
