Iridescent Glazed Globular Ceramic Raku Vase

This item is a spherical or globular ceramic vase featuring a distinctive iridescent glaze that shows qualities typical of the raku firing process or a metallic luster reduction glaze. The form is a classic 'seed jar' or orb shape with a narrow, unrimmed circular opening at the top, which reveals a dark, possibly matte black interior finish. The exterior surface displays a complex play of light, characterized by a metallic, pearlescent sheen that shifts between sage green, copper-red, and silvery-gold tones depending on the angle of illumination. The texture appears slightly granular or matte beneath the high-gloss luster, suggesting a sophisticated multi-stage firing. There are no readily visible maker's marks from this angle, though such pieces are often signed on the foot. The condition appears to be excellent with no visible cracks, chips, or surface abrasions, though the base remains obscured. The style is contemporary studio pottery, likely dating from the late 20th century to the present. The craftsmanship is evident in the perfect symmetry of the hand-turned or slip-cast form and the expert control over the atmospheric firing required to achieve such vivid iridescence.
