What exactly is stoneware? Porcelain’s utilitarian cousin, stoneware is a popular choice for everyday serveware. Stoneware is made out of clay that’s fired at approximately 2185° F, making it vitreous, or having the nature of glass; the fired clay becomes robust and resistant to chipping. What it loses in delicacy and sensitivity, stoneware makes up for in durability and versatility. Like this three-piece set, for instance: each serving bowl is microwave, and freezer-safe, making them suitable for reheating leftovers and storing food for later. Plus, they’re safe for use in the dishwasher, so after-dinner cleanup a breeze.
