RC History

The Royal Copenhagen Porcelain Manufactory was established May 1, 1775. From the beginning, each porcelain item was marked with three waves symbolizing Denmark’s three straits: the Sound and the Great and Little Belts.

For almost 100 years after the establishment of the Royal Copenhagen Porcelain Manufactory in 1775, the three waves were painted by hand. But in around 1870, the company began stamping the mark under the glaze – a tradition that lives on today.

The mark of the three waves has changed over time making it possible to date any piece of Royal Copenhagen Porcelain. Some of the factory marks are shown above. These have been used on porcelain with a blue underglaze decoration, namely the Christmas Plates, figurines and blue porcelain dinner services – all of which are essential not only to the company’s product line, but also to the beauty and elegance of any home.
