Excavations at Ahichchhatra in the Bareilly district in the Uttar Pradesha have also unearthed types of pottery wares belonging to the 3rd century B C. The wares found at the various strata show changes in the type, technique and decorative designs, and have been classified into three main groups, —viz., the early, the intermediate and the later groups. Grey wares predominate in the early group. Some of these have a black slip To this group belong the highly polished black or brown sherds of which the earliest associations at Ahichchhatra have not yet been determined. The black polished type is rare. The vessels of this early group are mostly plain with the exception of a few red wares bearing stamped designs. The group is generally charatcerised by the complete absence of painted decoration of any sort and of any evidence of the use of mould.
