Grayware pottery gets its color from being fired in a low oxygen atmosphere. The most common were jars, with bowls and effigies being rare. The first Grayware, made from 500-700 AD, were made by building up coils and scraping the surface smooth. Many pieces resembled the dried gourds that were used as containers previously.
Later Grayware showed more indented corrugated patterns with the rims of pots became more flaring. Whiteware started about the same time as Grayware. These vessels were painted with a thin white clay wash called a slip, and then painted with black or left white. The early works were deep bowls with a design toward the bottom of the bowl.
