The Therme Vals Tea Mug reinterprets Peter Zumthor’s architecture of stone, water, and silence into a tactile ritual of drinking. Formed through a dialogue between concrete and glass, it embodies the transition from the mountain’s weight and stillness to the warmth and fluidity of the spring. A thick concrete sleeve grounds the hand with mass and texture. Instead of a handle, subtle finger indentations are carved into the surface, inviting a measured, deliberate grip. Within it, a glass insert slides seamlessly into place, exposing only one face. The user’s thumb, resting on this plane, becomes the sole point of contact with the tea’s warmth—a quiet reminder of touch and presence. The mug’s heaviness turns drinking into a conscious act. Each lift carries the material memory of stone and heat, echoing the descent from Vals’s rugged exterior into its calm, luminous baths. It transforms a daily gesture into a moment of reflection between body, matter, and temperature.
