Stamped describes the technique of using a mold-made terracotta stamp for decoration. Designs are stamped or impressed (see
Impressed) into the soft clay surface of the vessel before it is painted. In Athens, stamped or impressed decoration first
appears around the middle of the 5th c. BCE, perhaps in the work of the Sotades Painter (see Sotades Painter). The ornament
generally consists of small and simple motifs, such as rosettes, concentric circles, palmettes, ovules, and tongues. Stamped
decoration usually appears on the interiors of drinking vessels, some of which have red-figure on their exteriors.
