Vessels: Holloware (mugs, pitchers/jugs, bowl and chamber pots.
Some forms of ceramic vessels exhibiting different surfaces were produced using small dried pieces of clay in several colours. The clay bits were pressed into a solid colour slip field, producing the encrusted look. Sometimes a lathe, a machine that rotates an object on its axis, was used to smooth the vessel’s surface. This technique produced a finely-grained granite-like design. This technique has also been referred to as “encrusted ware” (Towner 1963:47-48).
