Item Description: This is a beautiful sake cup (guinomi) by 仙石佳成 Sengoku Yoshinari, showcasing the stunning copper-red glaze technique known as shinsha. The piece features a captivating purple-red glaze that flows dramatically from the rim toward the interior, creating a mesmerizing gradient effect that transitions from deep burgundy to soft lavender and pearl gray tones. The exterior displays a sophisticated multi-layered glaze application, with the rich copper-red glaze cascading over a subtle base, revealing warm earth tones at the foot. The interior showcases a gentle gray-green celadon-like glaze with a fine crackle pattern (kannyu), adding depth and visual interest to the piece. The contrast between the vibrant outer glaze and the serene interior creates a harmonious balance that exemplifies refined Japanese ceramic aesthetics. Shinsha (copper-red) glaze is one of the most technically challenging techniques in ceramics, requiring precise control of kiln atmosphere and temperature. The successful achievement of this luminous red-purple coloration demonstrates the artist's mastery of firing techniques. The way the glaze pools and transitions creates unique patterns that make each piece truly one-of-a-kind. The foot ring reveals the natural clay body in a warm tan color, providing an elegant foundation for the glazed surface. The artist's signature seal is impressed on the base, confirming authenticity. This sake cup comes with its original wooden box (tomobako) inscribed with the artist's name, ensuring proper provenance. The compact size and comfortable form make this an ideal vessel for enjoying fine sake, while its artistic merit makes it equally suitable for display as an objet d'art. A refined example of contemporary Japanese ceramic craftsmanship that brings both beauty and functionality to the sake-drinking ritual.
