Uranium glass is a type of glass that is made with small amounts of uranium oxide, which gives it a distinctive yellow or green color. It was first produced in the early 19th century, and it quickly became popular for its bright, glowing color and unusual properties.

One of the most distinctive features of uranium glass is its ability to fluoresce, or glow, under UV light. This is due to the presence of uranium oxide, which absorbs UV light and re-emits it as visible light. Uranium glass is also known for its high refractive index, which gives it a bright, sparkling appearance.

In addition to its decorative qualities, uranium glass was also used for practical purposes, such as making laboratory equipment and lamp shades. It was also used in the production of jewelry and other decorative objects.

Today, uranium glass is highly prized by collectors and enthusiasts due to its unique properties and historical significance. It is often featured in museums and private collections, and it continues to be made by a small number of artisan glassmakers. However, due to concerns about the potential health risks of uranium, the production of uranium glass is now strictly regulated in many countries.
