AI Appraisal Estimate

This item is a contemporary hand-blown clear glass sculptural piece, likely a vase or decorative vessel, executed by the American glass artist Robin Mix. The object exhibits high-clarity lead-free or lead crystal glass with a complex, multi-lobed construction consisting of a central bulbous form from which several rounded, solid glass protrusions or 'feet' emerge. The craftsmanship demonstrates advanced flame or furnace working techniques typical of mid-to-late 20th-century American studio glass. A significant distinguishing feature is the artist's signature 'Robin Mix' applied in a gold-colored enamel or paint on the central body, rather than an etched signature, which is a notable stylistic choice. The glass appears to be in excellent condition with high refractive quality, showing no visible chips, cracks, or internal clouding (sick glass). The wall thickness appears substantial, indicating a heavy, high-quality piece. Robin Mix is known for his mastery of the Murrine technique; while this specific piece appears clear, it retains the organic, sculptural fluidity characteristic of his wider body of work from the late 20th century. The piece lacks a date but fits the aesthetic of the 1980s or 1990s studio glass movement.

This appraisal is based on a visual examination of a clear, multi-lobed hand-blown glass vessel attributed to Robin Mix. The piece displays a high level of technical proficiency, featuring a sculptural form with four distinct 'feet' and excellent clarity. The most notable feature is the signature 'Robin Mix' in gold enamel. While Mix is primarily celebrated for his complex murrine glass, his clear sculptural works represent an important facet of his studio practice from the late 20th century. Based on the provided imagery, the condition appears excellent with no visible scuffs, chips, or internal calcification. The secondary market for 1980s-90s American studio glass remains steady, though clear works generally fetch lower prices than his intricate mosaic pieces which can exceed $2,000. This specific form is relatively rare, adding a premium for collectors of Mix’s structural experiments. However, the use of a painted signature rather than an engraved one is atypical and warrants closer inspection. Authenticity cannot be definitively confirmed via images alone. A formal authentication would require physical inspection to verify the surface wear patterns (consistent with age), the pontil mark finish, and the chemical composition of the glass. I would also recommend seeking provenance documentation or a direct comparison with cataloged pieces from the artist’s Tunbridge, Vermont studio. This valuation assumes the piece is an authentic work by Robin Mix in mint condition.
