Vintage Murano Style Art Glass Centerpiece Bowl

This is a vintage hand-blown art glass centerpiece bowl, likely from Murano based on the provided context and visual characteristics. The bowl is shaped irregularly with a ruffled or wave-like rim, creating an organic, asymmetrical form. It is primarily clear glass with vibrant internal decoration. The internal design features swirled bands of color, including green, orange, blue, and what appears to be white or beige filigree or 'zanfirico' work near the center. There are also interspersed frit or chip-like inclusions of red and orange, adding texture and visual interest. The base is relatively thick and appears polished. The overall size, according to the context, is substantial, measuring 23 inches in length, 22 inches in width, and 8 inches in height, with a considerable weight of 12 lbs, indicative of its solid construction and material quantity. The craftsmanship appears to be of high quality, typical of Venetian glassblowing techniques. There are no immediately visible condition issues like chips or cracks in the provided image, but a thorough inspection would be required to confirm. There are no visible maker's marks or signatures in the image. The style is consistent with mid to late 20th-century Murano art glass.
