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
Jasperware exhibited in London in that year, with the initial showing restricted to 1,900 tickets, which soon sold out. Wedgwood's careful copies proved extremely useful when the vase was smashed in the British Museum in 1845, and then reconstructed by the restorer John Doubleday. The original edition was of 50 copies; in 1838 a further edition was cast in one piece, with the background then painted. Wedgwood jasperware can often be dated by the style of potter's marks, although there are exceptions to the rules: Jasperware was widely copied in England and elsewhere from its introduction, especially by other makers of
