Ruby stained long-stemmed glass

The item presented in the photographs is a long-stemmed glass featuring a deep ruby red or cranberry-colored bowl set atop a clear, slender stem and circular foot. The bowl has a bulbous, slightly tapering shape characteristic of vintage glassware, particularly cordial or liqueur glasses. The stem exhibits delicate internal detailing, including vertical patterns of trapped air bubbles or optical features that add texture and visual interest. Based purely on visual observation of the form and materials, the piece appears to be consistent with mid-20th-century decorative glassware production. The overall construction displays standard craftsmanship for pressed or blown glass tablewares, though there are no visible maker's marks, stamps, or signatures discernable from the provided images. Condition-wise, the glass appears largely intact with no obvious structural damage or repairs visible in the photos, though minor surface wear consistent with age and handling may be present upon physical inspection. The user-supplied context notes that the bowl exhibits an orange glow when exposed to a 365nm ultraviolet blacklight, which the owner attributes to the presence of cadmium or selenium content in the glass formulation; however, this claim remains unverified without professional chemical testing. The identification in the item name relies strictly on the observable physical attributes of color, form, and transparency without asserting any specific maker, brand, or exact period.

Based on what I can see in the provided photographs, this piece is a long-stemmed decorative glass featuring a deep ruby red or cranberry-colored bowl and an internal pattern of trapped air bubbles within the slender stem. I can't verify from a photo alone the exact age, manufacturing technique, or chemical composition of the glass. The owner identifies this as a liqueur glass exhibiting an orange glow under a 365nm ultraviolet blacklight, which is attributed to cadmium or selenium content; however, this claim remains an unverified user-supplied assertion without professional chemical testing. My value estimate of $45 to $85 assumes that the visual characteristics and the owner's notes regarding the glass formulation are accurate. Mid-20th-century decorative glassware and cordial glasses of this general aesthetic see modest, steady demand among collectors of vintage tablewares, though individual piece values fluctuate based on exact maker attribution and pristine condition. Would need physical inspection to confirm the presence of any subtle wear, structural flaws, or optical features. If physical inspection reveals that the item is a later reproduction, a modern replica, or simply an unattributed piece lacking the proposed cadmium or selenium characteristics, the market value would likely decrease to the $15 to $30 range. To fully substantiate the piece, one would need in-person examination by a decorative arts specialist, hallmark or maker verification if any obscure marks exist, and scientific testing to evaluate the glass formulation.
