Known as the conscience of Finnish design, Kaj Frank sought to remove excess in his work leaving only the essentials. In 1958, Franck realized his goal with the Kartio glass, which captured the perfect balance between material and geometric form. Simple, yet durable enough for everyday use, Franck mastered the creation of the basic drinking glass, which is a legendary design beyond any trend. The wide and versatile colour palette of Kartio perfectly represents Iittala’s knowledge of coloured glass.
