The Aurora Cup — Shino Wood-Fired Chawan

The Aurora Cup — Light in Motion on Clay

There are cups that look the same in every light. This is not one of them. Hold The Aurora Cup near a window, tilt it slightly, and watch what happens: copper-red, blue-violet, and liquid gold appear across the surface simultaneously, shifting and deepening as the angle changes. This iridescent metallic quality — produced by extreme reduction in the wood kiln at peak temperature — is among the rarest effects in wood-fired ceramics. It cannot be applied, planned, or repeated. It either happens in the fire, or it does not.

What Makes This Cup Exceptional: The iridescent surface is the defining characteristic of this cup and the primary reason for its place at the top of this collection. In certain light — direct sunlight, candlelight, or a warm lamp held close — the entire exterior surface shifts between metallic copper, deep blue-purple, and warm amber-gold. These are not surface coatings or applied finishes; they are structural colours produced by the interaction of iron oxides and carbon in the kiln atmosphere during firing. The effect is permanent and deepens with use as the cup is warmed repeatedly over time.

Glaze & Surface: The base glaze is a dense, complex layering of iron-rust brown, olive-green, and sandy ash deposits, textured throughout with fine mineral pinholes and organic spotting. Over this foundation, the reduction colours sit as a luminous second layer — visible most clearly across the upper shoulder and rim of the cup, where the glaze was thickest and the kiln atmosphere most intense. The rim carries a smooth accumulation of dark iron-brown glaze; the interior is a warm, deep reddish-brown, plain and functional.

A Note on Condition: The junction between the exterior wall and the foot ring is uneven in places — the glaze pooled and set irregularly at the base during firing. This is visible on close inspection and does not affect the cup's function or stability. It is disclosed honestly here as part of this cup's complete character.

Form & Feel:

• Full, generous chawan form — wide belly, slightly inward rim
• 410g weight — the heaviest cup in the collection; substantial and grounding
• Highly tactile exterior — textured mineral surface with complex depth
• Iridescent metallic surface — most visible in direct or raking light
• Small foot ring — slightly irregular at the base junction; stable on flat surfaces

For the Art of Tea: The weight and wide form make this an outstanding matcha bowl or gongfu sharing cup. The iridescent surface is particularly striking when the cup is warmed — heat intensifies the metallic shimmer. This is a cup to use slowly, in good light, with tea you want to pay attention to.

One of a kind. Wood-fired in a single kiln firing. Never to be repeated.

Care

Suitable for contact with tea. Hand wash gently and avoid abrasive cleaners. Variations and firing marks are part of this one-of-a-kind handmade piece.
