Art glass bowl with internal red starburst motif (unverified maker)

This is an art glass bowl featuring an asymmetrical, multi-pointed leaf or teardrop shape with three distinct protruding corners or spouts. The piece is constructed primarily from clear or pale greyish-tinted glass, showcasing a striking internal inclusion or encased design at the center that resembles a bright red starburst or sun motif with undulating rays. The glass appears thick and heavy, with smooth, polished surfaces and soft, rounded edges characteristic of hand-blown or free-formed studio glass techniques. There are no clearly visible maker's marks, signatures, or acid stamps apparent in the provided photograph; therefore, any specific attribution remains entirely unverified. The overall aesthetic is consistent with mid-to-late 20th-century modern art glass design, possibly originating from Scandinavian, Murano, or contemporary studio glass traditions, though this is purely a stylistic assessment based on visual characteristics. Condition-wise, the bowl appears generally clean with typical light surface wear consistent with gentle handling and display, though microscopic flaws, minor scratches, or base wear cannot be ruled out without a physical inspection. The attribution in the descriptive text relies entirely on visual observation of the form and internal decoration rather than documented provenance or signed marks.

Based on what I can see in the provided photograph, this art glass bowl features an asymmetrical, multi-pointed form with a striking internal red starburst motif. The piece appears thick and heavy with smooth, polished surfaces, consistent with mid-to-late 20th-century studio glass traditions such as Scandinavian or Murano design. However, I cannot verify the exact maker, origin, or production date from a photo alone, as there are no clearly visible signatures, maker's marks, or acid stamps. A physical inspection would be needed to confirm the glass type, weight, and any microscopic base wear or flaws. My value estimate of $300-$500 assumes the attribution to mid-century modern art glass is correct and that the piece is of good quality. General market demand for unbranded mid-century studio glass remains steady among collectors of modern decorative arts, though pieces lacking documented provenance or clear signatures typically trade at lower price points. If this bowl were to turn out to be a later reproduction, a modern copy, or simply made 'in the style of' mid-century studio glass without a specific maker, the value would likely decrease to the $75-$150 range. To establish a stronger attribution or confirm authenticity, an in-person examination by a specialized glass expert, detailed provenance documentation, and a thorough search for elusive signature etches under magnification would be necessary.
