Heart-shaped pressed glass vessel in the manner of uranium glass

This item appears to be a heavy-walled, heart-shaped glass vessel, likely a small bowl or novelty dish, featuring a 'heart-within-a-heart' design where the interior cavity mimics the exterior profile. The user notes suggest this is a heart-shaped vase and questions if it is uranium glass. Visually, the glass exhibits an intense neon green fluorescence under what appears to be ultraviolet (UV) lighting, which is stylistically consistent with uranium glass (also known as Vaseline glass). However, without a Geiger counter test or spectral analysis, this identification remains a hypothesis as some modern manganese-pressed glass can also react under certain light waves. The object has thick, rounded rims and a flat base, consistent with 20th-century mass-produced pressed glass techniques. No maker's marks, signatures, or labels are visible in the provided image to confirm a specific manufacturer like Fenton or Mosser. The condition appears good with no obvious chips or cracks visible, though there is a small amount of household dust or surface debris. The vibrant glow suggests a piece meant for display. All attributions to material composition and user-supplied claims are unverified and subject to in-person testing.

Based on my visual examination of the provided images, this object appears to be a pressed glass heart-shaped vessel. The user notes suggest this is 'uranium glass,' and while the intense green fluorescence under UV light is characteristic of such material, I cannot determine the chemical composition solely from a photograph. Physical testing, such as a Geiger counter reading, would be necessary to distinguish between uranium glass and modern manganese-bearing glass that can produce a similar glow. I am also unable to verify a specific maker, as no labels or signatures are visible; the thick-walled construction is consistent with 20th-century mass-produced novelty wares. The value estimate of $45–$85 is based on the assumption that the item is indeed uranium glass of mid-20th-century manufacture in good condition. Items of this type currently see steady interest from collectors of 'glow' glass and novelty Valentine-themed decor. However, if the piece is a contemporary reproduction or lacks the specific uranium content sought by enthusiasts, the market value would likely decrease to the $15–$25 range. To confirm the identity and potential value, an in-person inspection by a glass specialist and scientific verification of the glass's additive properties would be required. My estimate assumes the glass is free of internal heat cracks or minor chips not visible in the low-resolution images provided.
