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 tactile surface generated by molten mineral glazes, distinct fragments possessing differing pigments and melting points are layered and co-fired. Within the kiln, these glaze shards melt, bleed, and fuse into unpredictable boundaries and organic strata. Because the movement, dispersion, and thermal aggregation change with each firing cycle, no two surfaces are ever alike. Within a disciplined architectural framework, the ring captures the spontaneous ornamentation born of heat and raw earth.
-
Color & Glaze Characteristic (Alabaster): Luminous shards of cream, ivory, and soft pale amber melt together across the surface to form a dense, quiet terrain reminiscent of carved alabaster. As the light tones fuse under heat, they settle into gentle layers with subtle crystalline structures suspended beneath the glassy surface. The shifting, softened boundaries evoke the cross-section of weathered stone—carrying a warm, luminous stillness that feels lit from within.
