For her fourth design for Mutina, Italian designer Patricia Urquiola strikes with a collection of tiles made from glazed porcelain. The smooth 20 mm by 20 mm tiles are intended to be used in a patchwork configuration. The collection contains three base colors (white, light gray, and dark gray), and nine pattern options. The 10mm-thick tiles are resistant to sudden changes in temperature and chemical agents. The line is VOC-free and features partial use of recycled powders.
