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 and the Wedgwood formula was gradually adopted by most manufacturers. One important ware of note however is pearlware, of which there was an increase around 1779. Pearlware is distinct from creamware in having a blue-tinged glaze produced by the use of cobalt and a body somewhat modified to produce a ware that was slightly greyish in appearance.
