Art glass bowl

This is a decorative art glass bowl featuring a swirling, marbled pattern of light blue and white glass. The bowl has an irregular, handkerchief or pinched-rim shape with undulating sides that rise to uneven peaks, creating a dynamic visual effect. The interior base is flat and square-ish, transitioning smoothly into the organic, free-form walls. The glass has a glossy finish with translucent and opaque layers swirling together to mimic natural stone or fluid movement. Regarding physical condition, there are some minor surface scuffs, light dust accumulation, and small spots of residue visible inside the basin, consistent with being displayed or stored in an open environment. There are no visible maker's marks, stamps, or signatures present on the visible portions of this piece, making its exact origin, manufacturer, and date of production unverified. The overall aesthetic is suggestive of mid-century modern or contemporary studio glass craftsmanship, known for hand-blown techniques involving cased or multicolored glass layers. The attribution rests entirely on the visual characteristics of the glasswork, as no identifying text or labels can be observed in the image.

Based on what I can see in the photograph, this decorative art glass bowl features a swirling light blue and white marbled pattern with an irregular, pinched-rim shape. The piece exhibits a glossy finish and a fluid aesthetic that suggests mid-century modern or contemporary studio glass craftsmanship. I cannot verify from a photo the exact manufacturer, date of production, or composition, as there are no visible maker's marks, stamps, or signatures present on the available surfaces. Furthermore, physical condition details such as minor surface scuffs, light dust, and residue inside the basin can only be partially assessed visually and would need physical inspection to confirm the extent of wear. My valuation range of $150 to $300 assumes the piece is a quality example of mid-century or contemporary studio art glass with these visual characteristics. General market demand for unbranded studio glass of this type remains steady among decorative arts collectors, though pieces lacking a documented attribution or signature typically command modest prices. If this item were determined to be a later mass-produced reproduction, a replica, or simply made 'in the style of' studio glass rather than a hand-blown artisan piece, the value would likely decrease to the $40-$80 range. To establish a more precise value and explore potential attribution, an in-person examination by a glass specialist, potential expert appraisal, and a thorough search for subtle signatures or pontil marks would be necessary.
