Handmade art glass decorative bowl

This is a hand-blown art glass decorative bowl featuring a distinctive organic, asymmetrical form with an elongated rim profile. The piece is constructed primarily of clear glass encased or layered with swirling bands of deep cobalt blue and lighter translucent blue glass, creating a dynamic optical effect as the colors wrap around the interior and exterior of the vessel. The surface is smooth and polished, exhibiting a glossy finish consistent with mid-century or contemporary studio glass techniques. There is no visible maker's mark, signature, or stamp directly readable on the surfaces shown in the image. The identification is purely descriptive based on the visual characteristics of studio glass artistry. The piece appears to be in overall good visual condition with no obvious chips, cracks, or major structural damage apparent from this angle, though minor surface wear or handling marks cannot be ruled out without physical inspection. The style suggests mid-to-late 20th century studio production, reflecting techniques commonly associated with Murano or Scandinavian art glass traditions, though no specific attribution is asserted due to the absence of identifying marks. The craftsmanship displays good clarity and fluid movement within the glass matrix, characteristic of free-blown studio art glass objects.

Based on what I can see in the photograph, this hand-blown art glass decorative bowl exhibits a dynamic organic form and striking cobalt blue coloration consistent with mid-to-late 20th century studio glass traditions, such as those associated with Murano or Scandinavian production. The fluid movement within the glass matrix and the polished finish suggest quality craftsmanship. However, I can't verify the exact maker, exact period of manufacture, or complete structural integrity from a photo alone, as I would need physical inspection to confirm the absence of internal stress fractures, microscopic surface wear, or hidden tool marks. The piece bears no visible maker's mark or signature on the surfaces shown, meaning any attribution to a specific studio remains purely hypothetical. My value estimate of $300 to $500 assumes the piece is a quality mid-century studio glass production in the style of recognized art glass traditions. General market demand for unbranded mid-century art glass of this aesthetic remains steady among interior decorators and collectors, though pieces lacking documented signatures or labels typically command lower prices than fully attributed works by master glassblowers. If physical inspection were to reveal that this item is a modern reproduction, a contemporary replica, or a mass-market decorative copy rather than a mid-century studio piece, the market value would decrease significantly, likely falling into the $75 to $150 range. To establish a more precise valuation and explore potential attribution, an in-person examination by a specialized glass expert, alongside a search for elusive signatures or pontil marks, would be necessary.
