The business of Grays was set up in 1907 in Manchester, England by Edward Gray, pottery salesman. In 1912 the business moved to Hanley in Stoke on Trent, Staffordshire.
A name to conjure with and associated with Grays is the famous designer Susie Cooper who worked there between 1922 and 1929 reaching the level of Art Director. Cooper implemented floral, banding and strong geometric patterns and also produced lustre vases.
The company moved to larger premises in 1933 as production increased to include further ranges such as wall pockets, face masks and animal fancies, some of which were designed by Nancy Cato. Grays was bought out by Portmeirion Potteries in 1959 on the death of Edward Gray.
