Any Indian pottery with black rims and interior and red on the outside, due to firing in the inverted position, which was made beginning in the Iron Age. Characteristic forms include shallow dishes and deeper bowls. It first appeared on late sites of the Indus civilization and was a standard feature of the Banas culture. This ware has been found throughout much of the Indian peninsula with dates of the later 2nd and early 1st millennium BC. In the first millennium it became widespread in association with iron and megalithic monuments. In the Ganges Valley it post-dates ochre-colored pottery and generally precedes painted gray ware.
