Caspian Grey Reactive Glaze Mug

The simple, classic shape of our Caspian mug puts the focus on its beautiful grey reactive glaze. Undergoing chemical changes during firing, the glaze produces one-of-a-kind patterns and luminous, variable warm grey colors with taupe undertones. As it cascades down on the creamy white surface, the glaze transitions from light to dark, peppered throughout with unique markings and crackles. This intentional and desirable crazing occurs during firing, and the craquelure can develop more complexity over the years whenever the raw natural materials expand and contract. The glaze and its effects are food-safe but may temporarily discolor with certain foods.
