We may now summarize about the pottery wares of the Indus Valley Civilization. Brown glazed pottery articles formed the most common variety. Some polychrome pottery objects, decorated with floral and geometric patterns in black and white, on a red ground, have been found. The base of some vases has a row of lotus petals as an adornment. Potteries in some cases were slip glazed, but mostly painted. Painted potteries were generally made by painting or decorating on a slip applied to the body. Slips used were also coloured buff, cream, pink and red. These were made mostly of ferruginous clays, or by mixing red ochre with clay. The articles were finally burnt. Manganiferous hæmatite was used for black colour, and gypsum for producing white pottery.
