Red glass stemware goblet

This is a tall, elegant glass stemware goblet featuring a deep red, cranberry-colored bowl sitting atop a clear glass stem and circular foot. The bowl of the goblet has an ovoid or rounded silhouette that tapers gently toward the rim. The clear stem is notably slender and adorned with internal decorative texturing or pulled glass elements running vertically through the center, displaying careful craftsmanship. The circular foot is flat and provides a stable base for the elongated piece. There are no visible maker's marks, stamps, or signatures discernible from the provided images, leaving the exact manufacturer and production date unverified. The identification is based strictly on the visual characteristics of the glass shape and color composition. Regarding condition, the piece appears largely intact from the photographic evidence, showing normal surface reflections and no immediately obvious structural damage or major repairs, though a detailed physical examination would be necessary to assess micro-abrasions or manufacturing imperfections. The owner notes that the red bowl glows orange under a 365nm ultraviolet blacklight, which suggests the presence of cadmium within the glass formulation; however, this user-supplied chemical attribution remains entirely unverified by physical testing. Stylistically, the goblet is reminiscent of mid-century or vintage decorative glassware traditions, though it could span various production periods associated with cadmium-doped glass artware.

Based on what I can see in the provided photographs, this tall stemware goblet features a deep red cranberry bowl paired with a clear, internally textured stem and a flat circular foot. I can't verify from a photo whether the red coloration stems from specific historical production techniques or modern manufacturing, and a physical inspection would be needed to confirm the exact age, maker, and glass composition. The owner notes that the bowl glows orange under a 365nm ultraviolet blacklight, suggesting the potential presence of cadmium. Assuming this hypothetical attribution is correct and the piece aligns with vintage or mid-century cadmium-doped art glass traditions, the estimated market value generally falls in the $75 to $150 range, driven by demand for decorative colored glassware and novelty blacklight-responsive items. However, general market conditions for unbranded vintage stemware are modest. If this item turns out to be a modern reproduction, a mass-market replica, or simply an unattributed decorative piece lacking period significance, the value would likely decrease to the $20 to $40 range. To establish a more precise valuation and test the unverified user-supplied claims, physical examination by a specialist, professional handling to check for micro-abrasions, and scientific testing of the glass formulation would be required.
