Uranium Glass Plate Value Guide

This vintage green Uranium Glass plate, originating from the United States between 1920 and 1940, is a prime example of Depression-era 'Vaseline glass.' Its collectibility stems from the unique addition of uranium oxide to the glass melt, which creates a mesmerizing luminescence that remains a staple of mid-century glass collections.

What Is Uranium Glass Plate Worth?

The typical price range for Uranium Glass Plate is $45 - $45 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• The intensity and consistency of the glow under UV light significantly impact the $45 market valuation.
• Physical condition, specifically the absence of 'flea bites,' chips, or surface scratches from the 1920-1940 period.
• The complexity of the pressed glass pattern and the specific shade of green or yellow-green.
• Historical provenance and confirmation of its United States origin during the peak era of uranium glass popularity.

How to Identify Uranium Glass Plate?

• Verify the signature greenish-yellow tint characteristic of 1920s-1940s American glass production.
• Use a 365nm or 395nm ultraviolet light to confirm a bright, neon green glow caused by uranium oxide.
• Check for typical Depression-era manufacturing marks or patterns consistent with US glass houses of the early 20th century.
• Examine the glass for a slight oily or 'vaseline' texture common in authentic uranium-infused pieces.

History of Uranium Glass Plate

Uranium glass, also known as 'Vaseline glass', gained popularity in the late 19th and early 20th centuries. Its distinctive greenish-yellow glow under ultraviolet light is due to the small amount of uranium oxide added to the glass mixture. Though the use of uranium in consumer products declined after World War II, due to concerns over radioactivity and government regulations, these pieces remain highly sought after by collectors for their unique luminescence and historical significance.
