Pilkington Tile and Pottery Company was established in 1892 in England. The company made small pottery wares, like buttons and hatpins, but soon started decorating vases purchased from other potteries. Pilkington did not start producing pottery as separate from tile until 1897. By 1903, the company had discovered an opalescent glaze that became popular on the Lancastrian pottery line. The manufacture of pottery ended in 1937. Pilkington's Tiles Ltd. has worked from 1938 to the present.
