A wise old antique dealer just gave me a valuable tip … Royal Copenhagen pieces can be distinguished by the crown mark or the distinctive three waves. But if you’re buying twentieth century pieces there’s a very simple way to tell whether they were produced before or after 1969. A beehive with the waves across demonstrates that the piece was made at the Aluminia Faience factory, which merged with The Royal Copenhagen Porcelain Manufactory in 1882.
In 1969 the Aluminia name was changed to Royal Copenhagen Denmark and from then on pieces were marked with three wavy lines and the word Fajance (Faience)
