Art glass bowl (unverified maker)

This is an art glass bowl featuring an asymmetrical, free-form, handkerchief-style silhouette with heavily pulled and ruffled rims, including one prominent, elongated vertical peak. The piece is constructed from multiple layers of colored studio art glass, displaying an iridescent, opalescent or mother-of-pearl exterior finish that transitions into soft translucent pastel tones. The interior bowl base features concentric swirls of pale yellow, green, and a central vibrant pink or magenta core, creating a dynamic visual depth. No maker's marks, signatures, or stamps are visible from the angles shown, though the overall technique and color palette are consistent with mid-to-late 20th century studio art glass or Venetian Murano traditions. The item appears to be in good overall condition with no obvious chips or cracks visible in the photograph, showing standard light surface wear commensurate with age and handling. Craftsmanship indicators include smooth polished rims and a well-finished pontil area on the unseen underside. The identification of this piece is based entirely on its visual aesthetic, form, and glass-working techniques, as no identifying text or hallmark is present to confirm the specific maker or exact period of production.

Based on what I can see in the photograph, this art glass bowl features an asymmetrical handkerchief-style silhouette with pulled rims, an iridescent mother-of-pearl exterior finish, and concentric interior pastel swirls reminiscent of mid-to-late 20th century studio art glass or Venetian Murano traditions. The piece appears to be in good overall condition with no obvious chips or cracks visible, showing only standard light surface wear. I cannot verify from a photo whether the piece is truly Murano-produced or made by a specific studio, as no maker's marks or signatures are visible. The estimated value range of $150 to $300 assumes the attribution to mid-century studio art glass is correct, reflecting typical market behavior and current buyer demand for decorative pieces of this type and aesthetic. This valuation depends heavily on physical attributes such as glass quality, weight, and pontil finish. If the item were to turn out to be a modern reproduction, mass-produced replica, or an unattributed decorative piece 'in the style of' mid-century glass, the market value would likely decrease significantly, perhaps dropping to the $40 to $80 range. To confirm the precise origin, period of production, and craftsmanship, one would need physical inspection by a qualified specialist, a search for elusive signatures or pontil characteristics, and potential consultation with glass art experts.
