About This Piece
The Square Ring introduces geometric discipline to organic form by layering a square profile over smoothly curved ceramic volume. While maintaining a soft, comfortable mass against the hand, the upper plane is gently sculpted into a soft square—creating an intriguing dialogue between straight lines and rounded contours that shifts depending on the viewing angle.
Focusing intently on the surface generated by molten glass and fire, distinct shards of glaze possessing differing pigments and properties are layered and co-fired. During the kiln process, these glaze fragments melt, bleed, and coalesce into unpredictable boundaries and organic strata. Because the flow, dispersion, and crystalline aggregation change with every single firing, each piece yields a completely unrepeatable depth and pattern. Within a disciplined architectural framework, the ring captures the spontaneous ornamentation born of heat and chemistry.

Color & Glaze Characteristic (Verdite): Centered around a deep, grounding forest green, Verdite merges fused fragments of teal, blue-green, and muted grey glazes. The resulting surface reveals stratified mineral-like traces, clustered crystal formations, and delicate suspended particles reminiscent of a sliced gemstone cross-section. Verdite is the colorway where the serendipitous nature of kiln firing is most vividly expressed.
