Creamware cheap, good-quality, mass-produced creamware to Europe had a similar impact on Continental tin-glazed faience factories. By the 1780s Josiah Wedgwood was exporting as much as 80% of his output to Europe. Creamware is made from white clays from Dorset and Devonshire combined with an amount of calcined flint. This body is the same as that used for salt-glazed stoneware, but it is fired to a lower temperature (around 800 °C as opposed to 1,100 to 1,200 °C) and glazed with lead to form a cream-coloured earthenware. The white clays ensured a fine body and the addition of flint improved its
Creamware to outside specialist enamellers or transfer-printers for decoration – decoration in-house was only gradually adopted. For this reason, several manufacturers usually shared the same decorator or printer and tended to use the same or very similar patterns. Collectors, dealers and curators alike were frustrated in their efforts to ascribe pots to individual factories: it is frequently impossible to do so. Archaeological excavations of pottery sites in Staffordshire and elsewhere have helped provide some better-established typology to enable progress in attribution. Italian versions of creamware were known as terraglia, or "creta all'uso inglese" ("earthenware in the English manner"). They were produced
