Chamber pot, 11 x 8.75 x 7.5 inches. Black transfer with polychrome clobbering. Printed maker's mark for Ralph Hammersley & Son. Painted pattern number "1350." The impressed "5/84" indicates a form manufacture date of 1884. This pattern features circular cartouches filled with radiating forms and geometric designs placed amongst trailing vines of lanceolate leaves and five-petalled flowers. The border around the body rim and handle consists of a geometric patchwork of hatched shapes.

In 1862 Ralph Hammersley started manufacturing with a Mr. Eardley at the Church Bank Works in Tunstall. In 1868 Eardley left the business and Ralph Hammersley continued on his own at the Church Bank Works until 1870, when he moved to the newly rebuilt Over House Pottery in Burslem. “The new manufactory was opened in 1870 by Ralph Hammersley, who removed here from the Church Bank Pottery at Tunstall and who had previously been engaged for twenty years with Mr. Challinor. In [1885], the firm’s style was changed to Ralph Hammersley & Son and as such remained until sold in 1905 to T. Gater.” (Jewitt's Ceramic Art of Great Britain 1800-1900) It is probable that Ralph Hammersley died in December 1882 and the business was continued by his son Thomas Gallimore Hammersley in partnership with Margaret Hammersley and Susan Annie Corn. In November 1897 Susan Annie Corn retired from the business. The business closed in 1905 and the works were sold to Thomas Gater.
