Rosenthal Studio-Line Dinnerware TAC o2 Weiss Dinner Plate - TAC is true to Walter Gropius' principles. Built on geometric forms, the simple circle and the seamless globe are the primary inspirations for this modern, streamlined collection. The ancient shape of the Chinese tea bowl had been the source of inspiration for Walter Gropius. Purist design, based on simple geometric shapes, lends TAC a timeless poetry. Decors on slightly translucent porcelain emphasize the features of this icon of Bauhaus design.
