This factory produced goods from the 1750`s mainly known as ' dry edged figures ' because the base left an edge of white biscuit from the glaze retraction. In 1756, the factory was taken over by William Duesbury, (1925 - 86) a banker called John Heath and André Planché, a china maker for Derby. It was then officially called the Derby Porcelain factory. These wares are known for a glassy body and almost translucent enamel. Often the design imitated wares from the Meissen and Chelsea factory, some goods even had forged on them Chelsea's official mark. From 1770 the factory was known as the Chelsea-Derby period, as Duesbury had acquired the Chelsea factory. The French factory Sèvres provided an influence, and the factory also began to produce the ' biscuit figure'. The best are of the Royal family. In 1811 it was taken over by Robert Bloor.
