Uranium Glass Beads: A Collector's Guide for Jewellery Makers

he Fascinating World of Uranium Glass Beads: A Collector's Guide

If you've ever held a bead up to a UV light and watched it glow an eerie, otherworldly green, you've experienced the magic of uranium glass. Also known as Vaseline glass, uranium glass has captivated collectors, jewellery makers, and curiosity seekers for well over a century — and it's easy to see why.

What Is Uranium Glass?

Uranium glass is glass that has been manufactured with small amounts of uranium oxide added to the mix. This gives the glass its distinctive yellow-green colour in natural light, and its spectacular fluorescent glow under ultraviolet (UV) light. The uranium content typically ranges from trace amounts up to around 2% by weight, which is enough to produce that iconic glow without posing any significant health risk under normal handling conditions.

The name "Vaseline glass" comes from its resemblance to the pale yellow colour of petroleum jelly, though the term is sometimes used interchangeably with uranium glass depending on who you ask.

A Brief History

Uranium glass has been produced since the 1830s, with Bohemia (now the Czech Republic) being one of the earliest and most prolific producers. It became enormously popular in the Victorian and Edwardian eras, appearing in everything from tableware and vases to decorative beads and jewellery components. Production slowed significantly during and after World War II when uranium was restricted for military use, making pre-war pieces particularly collectible today.

After the war, production resumed and uranium glass continued to be made through the latter half of the 20th century, though never quite reaching its former heights of popularity. Today it enjoys a strong revival among collectors and jewellery makers who are drawn to its unique aesthetic and historical charm.

Uranium Glass in Jewellery Making

Uranium glass beads are a stunning choice for jewellery making. In daylight they have a soft, warm yellow-green tone that pairs beautifully with gold-filled wire, brass, and copper. Under UV light — at a festival, club, or black light setting — they transform into glowing focal points that never fail to draw attention.

These beads work particularly well in wire-wrapped pendants and earrings where their translucency can be fully appreciated. The light passes through them in a way that solid beads simply cannot replicate, giving finished pieces a luminous, almost magical quality.

Is Uranium Glass Safe?

This is the question most people ask first. The short answer is yes — uranium glass is safe to handle and wear as jewellery. The radioactivity is extremely low, comparable to many naturally occurring materials. It is not safe to eat from or drink from damaged uranium glass, but as decorative beads in jewellery, they present no meaningful risk. Always buy from reputable suppliers and enjoy them with confidence.

Where to Find Uranium Glass Beads

Vintage uranium glass beads can be found at antique fairs, specialist bead suppliers, and online marketplaces. Look for that telltale yellow-green colour and always test with a UV torch to confirm authenticity — genuine uranium glass will glow bright green every time.
