Please Note
I am an antique and vintage seller. All vintage and antique items have flaws. That is the nature and charm of aged and well-loved decor. If you are looking for pristine new decor, please do not purchase vintage or antique items from my shop. Everything I carry will show signs of age, use, and history. Please look closely at all photographs and read the description carefully before purchasing.
Strong green UV fluorescence and above-background radiation-meter response, both consistent with uranium glass. Not lab-tested by XRF.
Beautiful large circa 1930s–1940s uranium glass covered candy dish featuring an elegant floral and cherry motif with gorgeous pressed details throughout the glass. This stunning piece glows beautifully under black light and makes an exceptional display piece for both uranium glass collectors and lovers of romantic vintage décor.
The octagonal shape, domed lid, and raised botanical pattern give this piece incredible visual presence. Large naturally occurring bubbles scattered throughout the glass add wonderful character and authenticity that collectors love to see in early pressed glass.
This piece displays beautifully in daylight and absolutely comes alive under UV lighting.
Measurements:
• Approximately 6.5” tall
• Approximately 8.5” wide
Condition:
Excellent vintage condition overall. No cracks. One tiny fleabite under the inner rim/lip that is not noticeable during normal display and does not detract from the beauty of the piece. Lid fits properly and presents beautifully. Please review all photos carefully as they are considered part of the description.
Perfect for:
• Uranium glass collections
• Cottagecore décor
• Romantic vintage interiors
• Vanity or dresser display
• Tea room décor
• Trinket or candy storage
• Elegant glass collections
Circa:
1935–1942
Please Note:
Vintage glass may show light signs of age, manufacturing variations, bubbles, straw marks, mold lines, or minor wear consistent with age and use. These characteristics are considered part of the charm and authenticity of vintage glass.
Shipping Note:
I take exceptional care packaging fragile vintage items and use high-quality protective materials to help ensure safe arrival. I do not profit from shipping costs. Combined shipping is always happily offered whenever possible.
our uranium testing process:
Clear Glass Can Be Uranium Glass
Linked reference brief and practical testing protocol
Prepared for resale / listing verification use | Links checked May 2026
Bottom line
A clear or nearly colorless appearance does not by itself rule out uranium. Most vintage uranium glass is yellow, yellow-green, green, custard, Burmese, or other visibly tinted glass; however, authoritative glass references describe uranium glass as a composition category: glass colored by uranium oxide, produced in varied transparent and opaque colors. The defensible way to classify a piece is to combine UV response, color/glow behavior, and—when certainty matters—radiation or elemental testing. A visual “it is clear, so it cannot be uranium” statement is not reliable enough for resale attribution.
Key evidence from linked references
Reference
What it supports
How to use it
Oak Ridge Associated Universities / Museum of Radiation and Radioactivity
Uranium glass is broader than Vaseline glass; transparent yellow to yellow-green glass owes color to uranium; UV testing in the dark is described as a reliable way to identify uranium when glass glows rich green; ORAU also notes exceptions where uranium glass may not fluoresce.
Use as primary evidence for UV testing and for explaining that “Vaseline glass” is narrower than “uranium glass.”
Corning Museum of Glass, Glass Dictionary
Defines uranium glass as glass colored with uranium oxide and dates early reference to 1817, with Josef Riedel popularizing it after 1834.
Use as museum authority for the compositional definition.
Maryland archaeological glass composition quick-reference table
Lists uranium glass as made in varied colors, including transparent yellow and green and opaque/opalescent greens, whites, and pinks; identifies bright yellow/green UV response.
Use for the point that uranium glass is not just one visible color category.
Corning Museum of Glass conservation laboratory
Notes that uranium glasses fluoresce bright yellow/green and that other glass components can fluoresce too, including manganese and lead.
Use to avoid overclaiming: glow color matters, and some non-uranium glass also fluoresces.
Health Physics Society consumer-products fact sheet
States antique yellow/green glassware can contain detectable uranium and that uranium glass is valued for blacklight glow; notes even ordinary glass may be detectable due to potassium-40 or thorium-232.
Use for safety context and for explaining why a radiation meter reading alone needs interpretation.
Portable Spectral Services / micro-XRF article
Explains UV fluorescence and Geiger counter testing as methods and shows micro-XRF as elemental confirmation.
Use for the hierarchy of tests: UV screening, radiation screening, elemental confirmation.
Recommended testing workflow
1. 1. Start in a dark room. Turn off ambient light. Direct sunlight and bright room light can mask weak or edge-only fluorescence.
2. 2. Use both 365 nm and 395 nm UV when possible. A 395 nm blacklight is the common collector tool and often makes uranium glass glow vivid neon green. A 365 nm UV light may reveal repairs, residues, manganese, lead, or other fluorescence more clearly. Using both reduces false assumptions.
3. 3. Look for the uranium-style response. Uranium glass typically gives a bright, electric yellow-green to neon green glow that appears to come through the glass body, not just from dust, adhesive, surface residue, sticker glue, or edge reflections.
4. 4. Compare against known impostors. Manganese-decolorized clear glass often glows dull yellow, straw, peach, orange-yellow, or weak greenish/yellow, especially under 365 nm. Lead glass can fluoresce bluish-white. Soda-lime glass can give greenish-yellow responses. These are not the same as a strong uranium-green glow.
5. 5. Check the entire object. Test rim, base, handle, applied decorations, feet, and any fused or joined areas. Mixed-era or repaired glass can have different responses in different parts.
6. 6. Use a Geiger counter as supporting evidence, not the only proof. A reading above local background supports uranium or another radioactive component, but it does not identify the element by itself. Some uranium glass may read only mildly above background, and ordinary glass can sometimes show detectable potassium/thorium.
7. 7. For a high-value claim, confirm by elemental analysis. XRF or micro-XRF can detect uranium directly and is the strongest confirmation method short of lab analysis.
Simple seller-safe wording
When UV response is strong but you do not have elemental confirmation: “Clear / nearly colorless glass with strong green UV fluorescence consistent with uranium glass; tested under blacklight. Not lab-tested by XRF.”
When you have both UV and Geiger confirmation: “Strong green UV fluorescence and above-background radiation-meter response, both consistent with uranium glass. Not lab-tested by XRF unless otherwise stated.”
When glow is weak or yellow/orange: “UV-reactive glass; fluorescence may be from manganese or another glass component. Not represented as uranium glass.”

Seller claim strength
Recommended wording
Clear glass, bright electric green under 395 nm and 365 nm
Consistent with uranium glass, but still screen for residues/repairs.
Moderate without meter/XRF; stronger with meter.
“Consistent with uranium glass under UV.”
Clear glass, dull yellow/orange glow mostly under 365 nm
Often manganese-decolorized glass or another activator.
Weak for uranium.
“UV reactive; not represented as uranium.”
Green/yellow glass, bright green under UV
Classic uranium / Vaseline-type response if glow is strong.
Moderate to strong depending on meter/XRF.
“Uranium/Vaseline glass style; blacklight tested.”
Strong UV glow but Geiger counter does not rise above background
Could still be uranium at low level, or could be non-uranium fluorescence.
Moderate at best.
Avoid definitive uranium claim unless XRF confirms.
Above-background meter reading but weak/no green UV
Could be uranium that does not fluoresce, thorium, potassium, glaze, or another source.
Not enough to identify uranium.
“Detectable above background; composition not confirmed.”
Important cautions
• UV fluorescence is a screening test, not elemental proof. It is usually excellent for collector sorting, but XRF is the best confirmation for high-value or disputed pieces.
• Do not rely on visible color alone. “Clear” means appearance, not composition. Surface dirt, thickness, lighting, and formulation can all alter what the eye sees.
• Do not use glow alone to distinguish every radioactive glass. Uranium is famous for green fluorescence, but other activators can glow too.
• For food use, err conservative with vintage uranium glass. Display is generally treated as low risk, but avoid using questionable vintage pieces for acidic food/drink storage.
