History of Vintage Uranium Glass Marbles

Uranium glass, often called Vaseline glass for its yellow-green color, was popularized in the mid-19th century. These marbles contain small amounts of uranium, which causes them to glow a bright neon green when placed under a UV blacklight. Production of this glass declined significantly during the Cold War due to the regulation of uranium for nuclear weapons and energy.
