Fuerstenberg QI China, 5 pc. set, white and very light blue-green - made of porcelain. Set includes dinner plate, salad plate, soup bowl, cereal bowl, and tea cup. Dishwasher and microwave safe. Inspired by Asiatic philosophies of life, the 5-piece set of bowls redefines the concepts of surface and its tactile qualities. A special ceramic glaze in delicate blue-green, creates a silky, shimmering effect on the smooth inner surfaces seen here for the very first time on porcelain. In contrast, the unglazed exterior surfaces are polished to create a velvety sensation to the touch.
