Murano Art Glass Duck Figurine with Aventurine

This is a captivating art glass figurine depicting a duck, likely crafted in the Murano style, given the materials and technique. The duck stands upright on a clear glass base, which appears to be a stylized representation of water or foliage, infused with shimmering gold aventurine. The body and neck of the duck are primarily a rich reddish-brown or copper color, variegated with streaks and flecks of white and clear glass, giving the impression of feathers. This 'latticino' or 'zanfirico' type of internal filigree work is characteristic of Venetian glassmaking. The head of the duck features a distinct yellow or amber-colored beak and small, dark glass eyes. The overall form is graceful, with an elongated neck slightly curved, suggesting an alert or observing posture. The glass has a smooth, glossy finish throughout. The inclusion of aventurine, particularly in the base and subtly within the body, indicates a higher level of craftsmanship and adds a sparkling effect. No obvious chips, cracks, or repairs are visible from the provided images, suggesting it is in good vintage condition. The complexity of the internal glasswork and the artistic rendering of the duck suggest it could be from the mid-20th century to late 20th century, a period known for a resurgence in Murano art glass production and animal figurines. The lack of a visible maker's mark prevents definitive attribution, but the style strongly aligns with Murano glass traditions.
