At this point they moved from Sunderland Road Works, Longton to Alsager Pottery. Alsager China was used as a trademark. In 1970, Carborundum Limited bought the company. In 1976 Carborundum merged with Royal Worcester to form Royal Worcester Spode Ltd. In 1982 Palissy Pottery Ltd acquired the Hammersley name. But the Hammersley's Works was closed.
