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
Jasperware commissioned George Stubbs, and William Wood. William Hackwood was his chief in-house modeller, who was sometimes allowed to initial pieces. Using the celebrity of the aristocratic amateurs Lady Templeton and Lady Diana Beauclerk no doubt helped sales.
