Donna handcrafts this celtic knot mug on her potter's wheel in her New Hampshire workshop. Each one-of-a-kind ceramic mug is truly unique as it features a quartz stone on the handle, known for its stunning beauty and believed to have multiple uses for the enhancement of energy. Donna finishes each mug with layered glazes in soothing natural tones and a celtic knot embellishment. Each celtic knot mug measures 3.5 inches in diameter, stands 4.5 inches tall, and can hold up to 16 ounces. Handcrafted for Uno Alla Volta, from the heart and hands of the artisan.
