Beginning in 1771, Capodimonte began using the crown over Neopolitan N mark. This mark was used through the early 1800s when the Royal Factory closed.
Other companies began manufacturing porcelain in the Capodimonte tradition after 1925. Some of these pieces are marked with other company names or foil stickers in addition to a stamped variation of the crown over Neopolitan N mark.
