The Chelsea porcelain manufactory (established around 1743-45) is the first important porcelain manufactory in England; its earliest soft-paste porcelain, aimed at the market—cream jugs in the form of two seated goats—are dated 1745. The entrepreneurial director was Nicholas Sprimont, a silversmith by trade, but few documents survive to aid a picture of the manufactory's history. Early tablewares, being produced in profusion by 1750, depend on Meissen porcelain models and on silver prototypes, such as salt cellars in the form of realistic shells.
Chelsea was known for its figures. From about 1760 its inspiration was drawn more from Sèvres porcelain than Meissen.
In 1769 the manufactory was purchased by William Duesbury, owner of the Derby porcelain factory, and the wares are indistinguishable during the "Chelsea-Derby period" that lasted until 1784, when the Chelsea factory was demolished and its moulds, patterns and many of its workmen and artists transferred to Derby.
The factory history can be divided into four main periods, named for the identifying marks under the wares:
These early products bore an incised triangle mark. Most of the wares were white and were strongly influenced by silver design. The most notable products of this era were white saltcellars in the shape of crayfish. Perhaps the most famous pieces are the Goat and Bee jugs in 1747 that were also based on a silver model. Copies of these were made at Coalport in the 19th century.
In this period, the paste and glaze were modified to produce a clear, white, slightly opaque surface on which to paint. The influence of Meissen, Germany is evident in the classical figures among Italianate ruins and harbour scenes and adaptations from Francis Barlow's edition of Aesop's Fables. In 1751, copies were made of two Meissen services. Chelsea also made figures, birds and animals inspired by Meissen originals. Flowers and landscapes were copied from Vincennes.
