Kerttu Nurminen (née Rantanen; born 8 March 1943)[1] is a Finnish industrial designer of glass and ceramics.
Nurminen studied ceramics at the School of Industrial Design (Taideteollinen oppilaitos) in Helsinki (now part of the Aalto University School of Arts, Design and Architecture), in 1966–1970; however, she prefers glass over ceramic as material.
[1][2] Among her teachers was Kaj Franck, who was attached to the Nuutajärvi glass works [fi] at the time.
[2] Soon after graduating, Nurminen was recruited by Franck to join the design team at Nuutajärvi, where she remained for her entire 35-year-career, working alongside the likes of Franck and Oiva Toikka, eventually ending up alone as the company's last full-time salaried designer.
[2][3] She has designed a wide range of products, from mass-produced tableware to unique artworks, especially in glass.
