Mid-Century Modern Italian Emerald and Lime Green Incalmo/Fasce Glass Vase

This is a tall, rectangular art glass vase featuring a striking Mid-Century Modern aesthetic. The piece is constructed from thick, hand-blown cased glass, showcasing a vibrant lime green body accented by vertical white 'latticino' or 'fasce' style stripes. The design is indicative of Murano craftsmanship from the 1950s or 1960s, possibly from makers like Fratelli Toso or Venini. It features slightly rounded square corners and a thick, clear glass base that provides stability and a 'floating' visual effect for the internal color. The vertical white stripes are encased within the glass walls, demonstrating high-quality technical skill. There are no visible maker's marks or signatures in the image, which is common for export-ware from this period. The condition appears excellent with no visible chips, cracks, or flea bites; the surface retains a high-gloss finish with minimal surface scratches or signs of shelf wear. The color saturation is consistent and bold, making it a significant decorative example of the period's glass-working techniques.

I have carefully examined the visual characteristics of this Mid-Century Modern Italian art glass vase. The piece exhibits the 'a fasce' (banded) technique, where vertical canes are fused into the body—a hallmark of mid-century Murano craftsmanship. Specifically, the lime green core with encased white vertical stripes suggests an attribution to Fratelli Toso or possibly a high-quality export producer from the 1960s. The 'sommerso' style thick clear base provides the necessary weight and visual depth expected of authentic Venetian glass. Based on the images, the condition is excellent; the presence of a clear base without visible 'scuffing' or significant shelf wear suggests it has been well-curated. Market demand for Italian vibrant-colored glass remains steady, especially for rectangular forms which are less common than standard round shapes. Comparable pieces from known makers like Venini fetch significantly higher prices ($1,200+), but without a signature or foil label, the value is appraised based on the aesthetic quality and the style of the Toso furnaces. It is important to note that this appraisal is based solely on digital images. A definitive authentication would require an in-person inspection to verify the presence of 'pontil scars' on the base, the specific weight/density of the glass, and the presence of minute surface wear consistent with age. Scientific testing is rarely used for such glass, but provenance documentation or original import labels would be required to elevate the value into the premium collector's tier.
