Chelsea Grape pattern was made before 1840. A small bunch of grapes in a raised design, colored with purple or blue luster, is on the border of the white plate. Most of the pieces are unmarked. The pattern is sometimes called Aynsley or Grandmother. Chelsea Sprig is similar but has a sprig of flowers instead of the bunch of grapes. Chelsea Thistle has a raised thistle pattern. Chelsea grape-ware was never made by the Chelsea factory in England. Do not confuse these Chelsea patterns with Chelsea Keramic Art Works, which can be found in the Dedham category, or with Chelsea porcelain, the preceding category.
