Uranium Glass Flower Frogs, Pair

Story

During the early 20th century, hostesses used these heavy glass inserts to create elaborate, structured floral centerpieces. The secret ingredient in their bright green color is actual uranium, which makes these utilitarian objects glow a brilliant, sci-fi neon green under a UV blacklight.

Maker / Origin

While many glass houses of the era—such as Fenton, Cambridge, and Indiana Glass—produced these functional items, they were rarely marked. These companies kept American households cheerful during the Great Depression by producing affordable, colorful glassware that transformed ordinary tables into works of art.

Condition & Value

The photos show some typical light surface wear and minor flea bites or roughness around the edges of the holes, which is very common for utilitarian glass items that held metal-stemmed flowers. Overall, they appear structurally sound with no major cracks. Excellent condition with zero chips would command the higher end of the range.
