Hand-blown art glass bowl by Dale Chihuly, featuring an asymmetrical form consistent with the Macchia series. The piece displays a rich red ground with layered horizontal ribbing (optic pattern) and scattered black inclusions throughout. The rim is freeform and undulating, with a sculptural, fluid shape typical of Chihuly studio work. The interior shows a smooth gradient toward the center with visible depth and dimensionality in the glass. The underside is etched with a signature consistent with Chihuly studio markings (see attached image). In very good condition, no chips or cracks
