Reheat homemade chili at the office for a warm meal with this innovative, single serving mug from CorningWare. From CorningWare's smart Pop Ins line of kitchenware, the mug holds up to 22 ounces of a favorite beverage, soup, or vegetable dish. Constructed in fine stoneware, the fluted mug design adds simple elegance to a kitchen while performing multiple functions. Freezer-, refrigerator-, oven-, and microwave- safe, the mug enables quick and easy food preparation. Just add frozen minestrone, pop the mug into the microwave, and set your steaming soup on the dinner table. The included plastic lid keeps contents fresh and is heat-resistant for microwave use. Vented slots on the lid allow steam to exit while dishes reheat in the mug, preventing steam burns or messy content eruptions. To clean the mug, place in the dishwasher or wash by hand. Soaking stoneware may damage the mug's effectiveness. Avoid using abrasives that may cause scratches and blemishes.
