De Metalen Pot had several owners, including the Cruyck family and Wouter van Eenhoorn. It was later bought by Willem Cleffius Sr, and his son Lambertus Cleffius took over De Metalen Pot and managed it until 1691. He was the first Dutchman to produce red teapots similar to Chinese Yi Xing ware, and marked his objects with LC. His work showed a great understanding of spatial relationships, similar to the work produced by Samuel van Eenhoorn.
Lambertus van Eenhoorn (marked LVE), Wouter's second son, purchased De Metale Pot upon the death of his cousin Lambertus Cleffius in 1691. Van Eenhoorn recruited Guillaume Nieullet, a French modeller, specifically to produce complex designs, which can clearly be seen by the products manufactured during that period. These include famous items such as the bust of Prince William III of Orange.
Lambertus van Eenoorn played a major part in the development of the technically advanced use of colour from around 1700 in Delft. Many items were copies of the famille-verte Kangxi (1662-1722) porcelain that was being imported from China, and De Metalen Pot was the first factory to produce figures of human beings and animals.
