Gracie the White Swan Stoneware Mug. Swans have long been a revered symbol in mythology, religion, and the arts, often representing poise, prudence, devotion, and grace. Handmade on the potter's wheel with durable stoneware clay, each 14-ounce mug is high fired for a permanent finish that is lead-free, cadmium-free, microwave safe, and dishwasher safe. #ceramicmugs
