How Much Is Uranium Glass Worth?
Uranium glass — also called vaseline glass for its petroleum-jelly-like yellow-green color — contains small amounts of uranium oxide that make it glow brilliant green under ultraviolet (blacklight). Produced from the 1830s to the 1940s (and in limited quantities since), uranium glass has become a trendy collectible thanks to viral social media content showing its dramatic UV glow.

Why Knowing Your Uranium Glass Value Matters
Uranium glass has experienced a massive popularity surge thanks to TikTok and Instagram, where videos of glowing glass go viral regularly. This social media attention has brought a wave of new collectors into the market, pushing prices up for quality pieces. Victorian-era uranium glass with detailed patterns can be worth $50-$500+. Depression-era pieces are worth $10-$100+. Even small items like salt cellars and toothpick holders are worth $10-$30. The UV glow factor makes uranium glass uniquely exciting to collect — it's the only antique glass that literally lights up under a blacklight, giving it an almost magical appeal.
Key Factors That Affect Uranium Glass Value
Understanding what drives the price of uranium glass helps you get the most accurate valuation.
Era & Manufacturer
Victorian era (1840s-1900s): most valuable, $30-$500+. Edwardian/early 20th century: $20-$200+. Depression era (1930s): $10-$100. Post-WWII (limited production): $10-$50. Notable makers: Fenton, Northwood, Imperial, various European factories. Unmarked pieces are common and valued by age and quality.
Form & Size
Larger pieces are generally more valuable. Punch bowls and sets: $100-$500+. Vases and compotes: $30-$200. Bowls and plates: $15-$100. Cups and small pieces: $5-$30. Figural pieces (animals, novelty items): $20-$150+. Lamps and lighting: $50-$300+.
UV Glow Intensity
Stronger uranium content produces more dramatic glowing. Bright, vivid green glow under UV: full value. Moderate glow: standard pricing. Faint glow: may be a lower uranium content piece, somewhat less desirable to collectors seeking the dramatic effect.
Color & Type
Classic vaseline (yellow-green): most recognized and collected. Custard glass (opaque yellow with uranium): $20-$200+. Green transparent uranium glass: $15-$150+. Uranium-containing colors other than yellow-green exist and glow differently — these are less recognized but still collectible.
Condition
Perfect condition: full value. Minor chips: 30-50% reduction. Cracks: 50-80% reduction. Cloudiness or staining: 20-30% reduction. For decorative display purposes, minor imperfections are more acceptable than for serious collectors.

Uranium Glass Valuation FAQ
Is uranium glass safe?

The definitive test is UV light — shine a blacklight or UV flashlight on the glass, and genuine uranium glass will glow vivid green.

A small UV keychain flashlight ($5-$10) is the essential tool for uranium glass hunting.
Why is uranium glass trending?
Social media — particularly TikTok — has made uranium glass go viral. Videos of glowing glass under UV light are visually spectacular and easily shareable. This has introduced uranium glass to a younger demographic that finds the combination of vintage aesthetics, science (radioactivity!), and visual drama irresistible.
