Optic Swirl Dishware Appraisal

Optic Swirl Stemware Water Goblet

This item is a clear glass stemmed water goblet featuring a distinctive optic swirl pattern on the bowl. The piece is constructed from colorless soda-lime or lead glass, standing approximately 7 to 8 inches in height. The bowl begins with a flared rim and tapers downward, accented by diagonal ribbing that creates a rhythmic, light-catching spiral effect. The stem is multi-faceted or molded with a central baluster-style knop and a smaller rounded transition at the base of the bowl, providing both structural stability and an elegant aesthetic. The foot is flat and circular, typical of mid-20th-century mass-manufactured glassware styled after Depression-era or traditional patterns. Evaluation of the condition shows no immediate cracks or significant chips, though there is a visible price tag remnant or adhesive residue on the foot which can easily be removed. The glass possesses good clarity with minimal cloudiness. While no specific maker's mark is visible through the glass in this view, the style is consistent with mid-century American manufacturers such as Libbey, Tiffin, or Federal Glass, likely dating from the 1960s to 1980s. The craftsmanship is standard for production-line stemware, featuring seamless transitions but lacking the specialized hand-blown characteristics of high-end crystal.
