Creamware of these potteries would have been producing creamware. Whilst Staffordshire had taken the lead, creamware came to be developed in a number of large potting centres where stoneware was already being produced, eventually replacing stoneware entirely. These included Derbyshire, Liverpool, Yorkshire (including the Leeds pottery) and Swansea. Attribution of pieces to particular factories has always been difficult because virtually no creamware was marked prior to Josiah Wedgwood's manufacture of it in Burslem. At the time manufacturers frequently supplied wares to one another to supplement stocks and ideas were often exchanged or copied. In addition, factories usually sent out their wares
Japanese pottery and porcelain studied ceramic techniques in China and brought high-fired glazed ceramic to Seto in 1223.
