Uranium Glass Swung Vase Value Guide

This mid-century Uranium Glass Swung Vase represents a peak in American glassmaking, combining the radioactive allure of uranium dioxide with the dramatic, elongated silhouettes of the 'swung' technique. These pieces are highly collectible for their vibrant greenish-yellow hue and their ability to fluoresce brilliantly under ultraviolet light.

What Is Uranium Glass Swung Vase Worth?

The typical price range for Uranium Glass Swung Vase is $50 - $70 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• Height and dramatic stretch: Taller, more extreme 'swung' forms typically command higher prices within the $50-$70 range.
• Condition: The absence of chips, 'flea bites' along the fluted rim, or internal mineral staining significantly preserves value.
• Fluorescence intensity: The brightness of the glow under UV light is a primary driver for uranium glass enthusiasts.
• Color saturation: Deeper green hues or rare variations in the uranium glass mix can influence the final market price.

How to Identify Uranium Glass Swung Vase?

• Verify the presence of uranium dioxide by checking for a bright neon green glow under a 365nm or 395nm UV blacklight.
• Look for the characteristic 'swung' features, such as an elongated neck and unique, irregular fluted edges created by centrifugal force.
• Examine the base for a polished pontil mark or specific mid-century American manufacturer traits common to the 1950s-1970s era.
• Confirm the glass color is a translucent greenish-yellow, often referred to by collectors as 'Vaseline glass'.

History of Uranium Glass Swung Vase

Uranium glass, often called Vaseline glass, gained popularity from the 1880s to the 1940s. Its distinctive greenish-yellow hue comes from the addition of uranium dioxide, which also makes it glow vividly under ultraviolet light. The 'swung' technique involves reheating and stretching a glass piece, creating unique, elongated forms like this vase.
