Blown glass art vase with lattice pattern

This is a tall, elegantly proportioned art glass vase featuring a vibrant cobalt blue primary coloration overlaid with a contrasting diagonal white or pale yellow latticinio or ribbon pattern, creating a striking crisscross visual effect across the body. The vessel exhibits a tapering cylindrical or baluster silhouette, gently swelling in the lower middle section before narrowing toward the base, and expanding upward into a flared, flattened rim. The piece displays smooth reflective surfaces and clean lines indicative of free-blown or mold-blown studio glass techniques. There are no visible maker marks, signatures, or acid stamps discernable from the photograph; the visual characteristics are consistent with contemporary or mid-to-late 20th-century art glass production, potentially referencing Venetian or Murano traditions of zanfirico or latticino work, though this remains entirely unverified. The physical condition appears generally good upon visual inspection, showing typical high gloss and clear refraction with no glaring structural cracks or major chips evident from this angle, though minor surface wear cannot be ruled out without tactile examination. The identification rests strictly on visible stylistic elements such as the optical twist patterns and color contrast rather than any documented provenance.

Based on what I can see in the photograph, this tall art glass vase presents a vibrant cobalt blue body overlaid with a diagonal white latticinio ribbon pattern, evoking Venetian or Murano traditions of zanfirico work. The vessel exhibits a tapering silhouette and a flared rim with smooth reflective surfaces. However, I cannot verify the exact maker, studio, or exact period of production from a photo alone, as there are no visible maker marks or signatures discernable. My evaluation assumes the visual characteristics are consistent with mid-to-late 20th-century studio glass production. The physical condition appears generally good upon visual inspection, showing high gloss without glaring structural cracks, but I would need physical inspection to confirm the absence of minor surface wear, internal flaws, or pontil characteristics. General market demand for mid-century style decorative art glass remains steady among collectors of colored studio glass, though pieces lacking documented provenance or attribution generally trade in lower brackets. Assuming the attribution style is correct, the estimated market range is $300 to $600. If physical inspection were to reveal the piece is a modern replica, a generic reproduction, or simply produced 'in the style of' without studio pedigree, the value would likely drop significantly to the $75-150 range. To better establish value and potential attribution, an in-person examination by a specialized glass appraiser, detailed tactile inspection of the base and pontil mark, and research into potential studio origins would be necessary.
