Vaseline UV Glow Glass Marble Vintage Pendant Necklace

  • $ 3000

I attached a silver plated cap to a vintage vaseline glass marble. This comes with a 24 inch silver filled chain. The sphere has bubble inclusions and glows green under ultraviolet light. It is approximately 14mm in diameter.

Vaseline glass is often called by many different names including canary depression glass, custard, vaseline, and uranium glass. Trace amounts of uranium dioxide are added to silicate crystals during the melting process to create the bright lemon yellow color. It also glows a fluorescent green under black light. However, it is not radioactive and does not contain enough uranium to be harmful.

Uranium glass was popular from the 1880's to the 1930's. It was sold as tableware and other types of collectables, but production was discontinued when the availability of uranium was sharply curtailed during the Cold War. Most examples of vaseline glass date from that time period. In 1958 uranium was deregulated and it was then produced using depleted uranium. Today uranium glass is mostly made in Eastern Europe.
