How neat is this chart! ❤️ I bet you can find some awesome uranium pieces at Fisher’s!
Ever wonder why some vintage glass glows under a blacklight?
One of the questions we hear most often at Fisher’s is, “What makes that glass glow?” The answer depends on the elements used when the glass was made—and different UV light wavelengths can reveal different surprises!
✨ 395nm UV Light
💚 Uranium Glass
✨ 365nm UV Light
🩵 Manganese
💙 Cerium
💙 Cobalt
💙 Copper Oxide
✨ 250nm UV Light
🤍 Lead (along with certain plastics, minerals, glazes, paints, and other materials)
❤️ Cadmium and 💗 Selenium also produce stunning fluorescence under the right conditions, creating brilliant reds, oranges, and pinks.
Keep in mind that not every glowing piece is uranium glass, and not every vintage treasure reacts the same way. The wavelength of your UV flashlight makes a big difference in what you’ll see!
We’ve included this handy glow cheat sheet as a reference the next time you’re treasure hunting. Bring your questions—and maybe your blacklight—because you never know what hidden glow is waiting to be discovered at Fisher’s! 🌟🔦💚
