In 1969, Walter Gropius designed a collection of china for Rosenthal. Named after his atelier in Cambridge, The Architects Collaborative, TAC’s elegant and curious forms are pristine in white porcelain. Embellishing Gropius’ design would naturally be heresy to some purists. To others, it would reflect his belief in the collaborative process. In their update of the tableware, called TAC Big Cities, architect Bjarke Ingels of BIG and Danish industrial design studio Kilo teamed up to create an urban motif for the collection.
