to him, a "high degree of finish led to consider it as an imported ware or at least an imitation of the Roman Samian Ware". But in 1966 S. R. Rao in his report on Amreli rejected this possibility of a Roman influence. He insisted on an indigenous origin as none of the forms shared the shapes of Roman prototype. He presented a broad variety of vessel types consisting of clay suitable to that definition. Instead he referred to a similarity of vessels of Black Ware with polished surface [Black Polished ware] from the same site noted in layers beyond the first occurrence of RPW. According to Heidrun Schenk, the pottery defined as RPW consists of two very distinct functional groups. Thus, the subject needs more precise classification and dating. One group belongs to the local pottery development of a region around Gujarat—mostly domestic vessels like cooking pots. The core area of this group is western India, but it is also distributed elsewhere on the western littoral of the Indian Ocean. The other group are the very specialized types of the 'sprinkler' and 'spouted' water jars, that often go together. This special group is widely found in the eastern region of the Indian Ocean, throughout the South Asian subcontinent and South East Asia with many different fabrics. This group represents a later development continuing well into the Middle Ages. In particular, in Tissamaharama, in the Southern Province of Sri Lanka, a good stratigraphy is found. Early Red Polished Ware is often associated with the Northern Black Polished ware (NBP), and goes back to 3rd century BC. Malwa culture (1600 BCE - 1300 CE) in Madhya Pradesh and north Maharashtra Malwa culture was a Chalcolithic archaeological culture which existed in the Malwa region of Central India and parts of Maharashtra in the Deccan Peninsula. It is mainly dated to BCE, but calibrated radiocarbon dates have suggested that the beginning of this culture may be as early as 2000-1750 BCE. the unique aspect of the Malwa culture is they do not use potter’s wheel instead the whole process is done by hand. Jorwe culture (1000 - 700 BCE) in Maharashtra Jorwe culture was a Chalcolithic archaeological culture which existed in large areas of what is now Maharashtra state in Western India, and also reached north into the Malwa region of Madhya Pradesh. It is named after the type site of Jorwe. The
