Glazed stoneware ball vase, nuanced gray-blue tones, circa 1960

Glazed stoneware ball vase with a granite surface in a beautiful shade of blue-gray. The slightly metallic glaze features subtle variations evoking raw materials and mineral landscapes. The shape, tapering toward the neck, highlights the interplay of textures and the depth of tones. The piece is signed under the base, an undeciphered signature, likely that of a studio ceramicist active in the second half of the 20th century.
