Johannes Jacobus (Jan) van der Vaart was an influential Dutch ceramicist from the 20th century, known as founder of the abstract-geometric ceramics in the Netherlands.

The Princessehof Ceramics Museum is a museum of ceramics in the city of Leeuwarden in the Netherlands. The museum's name comes from one of two buildings in which it is housed: a small palace built in 1693 and later occupied by Marie Louise, dowager Princess of Orange. The other annexed building is the Papinga stins, a former stronghold from the 15th century. The museum buildings are of interest, and so are its collection of tiles, pottery, and ceramic sculpture.
