Uranium glass, known for its distinctive glow under ultraviolet light, is a fascinating collectible. While most people associate it with a greenish hue, uranium glass actually comes in a variety of colors. This article explores the different colors of uranium glass, providing insights into its composition and appeal to collectors.
What Colors Does Uranium Glass Come In?
Uranium glass is primarily known for its green color, but it can also be found in yellow, amber, and even blue hues. The color variations depend on the other minerals and metals mixed with the uranium oxide during production.
Why Does Uranium Glass Glow?
The unique glow of uranium glass is due to the presence of uranium oxide, which fluoresces under ultraviolet light. This property makes it highly desirable among collectors and adds an element of intrigue to its appearance.
Exploring the Different Colors of Uranium Glass
Green Uranium Glass
Green is the most common color for uranium glass. The characteristic green glow is due to the uranium content, which can range from 0.1% to 2% by weight. This color is often seen in vintage glassware and decorative items.
Yellow Uranium Glass
Yellow uranium glass, sometimes referred to as "Vaseline glass," has a pale yellow hue and a vibrant glow under UV light. The yellow color results from the inclusion of other elements like iron or sulfur during the glassmaking process.
Amber Uranium Glass
Amber uranium glass is less common but equally striking. The amber color is achieved by adding iron or other metal oxides, which can alter the glass’s hue while still allowing it to glow under UV light.
Blue Uranium Glass
Blue uranium glass is rare and highly sought after by collectors. The blue tint is created by adding cobalt or other blue-producing elements to the mixture. Despite its rarity, blue uranium glass retains the characteristic glow that makes uranium glass so distinctive.
How to Identify Uranium Glass Colors
Identifying uranium glass involves a few simple steps:
- Visual Inspection: Check for the typical green, yellow, amber, or blue hues.
- UV Light Test: Shine a UV light on the glass to see if it glows, indicating the presence of uranium.
- Expert Consultation: For rare colors like blue, consulting with a glass expert or collector can provide confirmation.
