Uranium Glass Flower Frog Value Guide

This 1930s Uranium Glass Flower Frog is a quintessential piece of American Depression-era glassware, blending utility with the era's fascination for vibrant colors. Its collectibility stems from the inclusion of uranium dioxide, which gives the piece a striking fluorescent glow that remains a favorite among glass enthusiasts.

What Is Uranium Glass Flower Frog Worth?

The typical price range for Uranium Glass Flower Frog is $40 - $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 around the delicate stem holes or base significantly reduce the $40-$50 market value.
• The intensity of the fluorescence under UV light can influence desirability among specialized uranium glass collectors.
• Rarity of the specific hole pattern or a unique geometric shape can push the price toward the higher end of the valuation range.
• Clarity of the glass, specifically the absence of 'sick glass' or permanent cloudiness from hard water deposits.

How to Identify Uranium Glass Flower Frog?

• Verify the signature neon green glow by placing the glass under a long-wave ultraviolet (UV) light source.
• Look for the characteristic transparent green 'Vaseline glass' tint common in United States production from the 1930s.
• Check for a multi-hole 'frog' design, typically featuring a domed or flat shape with symmetrical perforations for stem placement.
• Inspect for mold marks or slight bubbles in the glass, which are indicative of mass-production techniques used during the Depression Era.

History of Uranium Glass Flower Frog

Flower frogs became widely popular in the late 19th and early 20th centuries as a practical and decorative tool for floristry. During the Depression Era, colored glass, especially uranium glass which glows under UV light, was mass-produced, making items like these accessible and desirable. The presence of uranium gives the glass its distinctive green hue and fluorescent property.
