Stoneware Bowls Set of 4 are functional for every occasion. Beautifully shaped yet humble enough to act as a discreet backdrop to the perfectly arranged meal. The PILAR tableware collection was designed by Floz Design in Germany. Stoneware pieces include bowls, plates, mugs and serveware. PILAR stoneware is manufactured from clay, quartz and minerals such as calcite and is defined as a ceramic product. The stoneware is molded at very high temperatures using casting techniques. The high temperatures during the firing process make stoneware more stable than clay and less translucent than porcelain.
