Weight matters in a mug. Thin walls cool fast and feel like nothing in the hand, while high-fired stoneware is dense and vitrified, so it holds heat and feels like something worth holding. The Aria Holiday Mug is hand painted in Portugal with holly branches and berries, handcrafted into a softly organic shape rather than a precise one, and it shrugs off the knocks of a mug used every day through December. It takes the dishwasher and the microwave without trouble. Hand one to someone coming in from the cold, set a row out beside a pot of coffee on Christmas morning, and keep using them long after the decorations are down.
