Royal Sphinx Maastricht tableware

The image features the iconic green 'Windmill' mark underglazed on ceramic tableware, representing the historic Royal Sphinx Maastricht brand. Originally established by Petrus Regout in 1834, the company became a cornerstone of the Dutch ceramics industry in Maastricht. The windmill logo was particularly prominent on their earthenware and porcelain products during the mid-20th century.

Over the decades, the company underwent several mergers, famously becoming NV Sphinx-Gustavsberg and later part of NV Koninklijke Sphinx. Manufacturing historically took place in the Sphinx factory complex in Maastricht, Netherlands. Although the brand has a rich Dutch heritage, the production of ceramics under the Sphinx name in Maastricht ceased in the early 2010s. The brand name is currently part of the portfolio of Geberit, a Swiss multinational group specializing in sanitary products.
