Uranium Glass Measuring Cup Value Guide

This 1930s American-made measuring cup is a prime example of Depression-era kitchenware crafted with uranium dioxide. Its ability to emit a vibrant neon green glow under ultraviolet light makes it a highly sought-after specimen for both glass enthusiasts and science history collectors.

What Is Uranium Glass Measuring Cup Worth?

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

• Condition is paramount; chips or cracks in the glass significantly reduce the $50 market estimate.
• Clarity of the embossed measurement increments and the presence of original pouring spouts.

• Rarity of the specific manufacturer's mold or unique handle designs from the 1930s.

How to Identify Uranium Glass Measuring Cup?

• Verify the signature vivid green or yellow-green hue typical of 1930s American glass production.
• Use a 365nm or 395nm UV flashlight to confirm the characteristic bright fluorescent glow.
• Check for molded measurement markings and a thick, heavy base common to utilitarian kitchenware of the era.
• Look for minor bubbles or 'straw marks' within the glass which indicate authentic period manufacturing processes.

History of Uranium Glass Measuring Cup

Uranium glass, also known as Vaseline glass, has a fascinating history dating back to the 1830s. Its distinctive yellow-green glow under ultraviolet light comes from a small amount of uranium dioxide added to the glass mixture. Popular from the 1880s to the 1920s, its production declined significantly during World War II due to restrictions on uranium use for atomic weapons, making these older pieces highly collectible today.
