Holding warmth, weight, and quiet intensity, this ceramic Yam cup expresses the deep character of wood-fired stoneware through its surface and form. The softly cylindrical shape feels steady and reassuring in the hand, shaped slowly to retain the subtle irregularities that make each piece feel individual. Layers of copper, ember red, and smoky brown glow across the surface like cooling coals, guided by a painterly sensibility where clay becomes a record of heat, time, and movement. Crafted in stoneware and wood-fired, the cup is shaped by drifting ash, wandering flames, and shifting kiln atmospheres, creating natural flashing, soft textures, and unrepeatable markings. Ideal for tea, sake, espresso, or reflective sipping, the cup invites slow moments, tactile connection, and a deeper awareness of material and ritual.

Process & Craft


Each yam cup is handmade by master craftspeople using traditional studio pottery methods, beginning with wheel-thrown forms shaped from unique clay mixes prepared in-house. Natural, mineral-rich glazes are applied by hand, drawing from Japanese Mingei and Korean Buncheong influences that guide the studio’s design sensibility. Fired at nearly 1300°C, the stoneware develops remarkable strength and a glaze surface shaped by the dynamic play of fire, ash, and high-temperature reactions inside the kiln. Every piece is quietly distinct — a reflection of the kiln’s temperament, the hands that shaped it, and the experienced designers who curate its final aesthetic.

Sustainability Practices


Made in serene, low-waste pottery studios that prioritize mindful production. All materials used — clays, glazes, oxides — are natural and non-toxic. High-temperature firing ensures long product life, reducing breakage and replacement cycles. Crafted in small batches to support ethical production and minimize overconsumption. Each mug embodies a slow craft philosophy, valuing longevity over mass production.
