Uranium Glass Lamp Shade Value Guide

This bell-shaped lamp shade is a prime example of American craftsmanship from the 1920-1940 era, featuring the iconic inclusion of uranium oxide. Its ability to fluoresce a brilliant neon green under ultraviolet light makes it a highly sought-after piece for Depression-era glass collectors.

What Is Uranium Glass Lamp Shade Worth?

The typical price range for Uranium Glass Lamp Shade is $150 - $150 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• Pristine condition is vital, as chips or 'flea bites' around the fitter rim significantly reduce the $150 valuation.
• The intensity of the glow, determined by the concentration of uranium oxide used during production.
• Clarity of the glass, ensuring no 'sick glass' cloudiness or permanent mineral staining is present.
• Authenticity of the era, specifically pieces originating from the United States between the World Wars.

How to Identify Uranium Glass Lamp Shade?

• Verify the signature vivid green or yellow-green 'Vaseline glass' tint under natural light.
• Use a 365nm or 395nm UV light to confirm the intense, characteristic green fluorescence.
• Check for the specific bell-shaped silhouette common in United States production from 1920-1940.
• Inspect for period-accurate mold marks or hand-finished edges typical of early 20th-century manufacturing.

History of Uranium Glass Lamp Shade

Uranium glass, also known as 'Vaseline glass', gained popularity in the 19th and early 20th centuries for its distinctive fluorescent green or yellow hue, which glows under ultraviolet light. The inclusion of uranium oxide gave the glass its unique color and luminescent properties, making it a fashionable choice for decorative items and tableware before concerns about radioactivity led to its decline in widespread production. Today, it is a sought-after collectible due to its historical significance and unique aesthetic.
