Uranium glass used as lead-in seals in a vacuum capacitor Uranium glassware glowing under ultraviolet light. Uranium glass is glass which has had uranium, usually in oxide diuranate form, added to a glass mix before melting for colouration. The proportion usually varies from trace levels to about 2% uranium by weight, although some 20th-century ...
Uranium (0.1 to 2%) can be added to give glass a fluorescent yellow or green color. [8] Uranium glass is typically not radioactive enough to be dangerous, but if ground into a powder, such as by polishing with sandpaper, and inhaled, it can be carcinogenic. When used with lead glass with very high proportion of lead, produces a deep red color.
Cut glass wine glass made of lead glass. Lead glass, commonly called crystal, is a variety of glass in which lead replaces the calcium content of a typical potash glass. [1] Lead glass contains typically 18–40% (by mass) lead(II) oxide (PbO), while modern lead crystal, historically also known as flint glass due to the original silica source, contains a minimum of 24% PbO.

"Uranium glass jewelry can come in pretty much any color, even red and blue," she says. But, she cautions, resin, acrylic, and plastic have polymers in them that make them glow. However, if an ...
Like many uranium glass collectors, they are especially drawn to pearline, which was created by several companies, mostly in Britain, from the end of the 19th century into the 20th.
Uranium glass used as lead-in seals in a vacuum capacitor. Glass-to-metal seals are a type of mechanical seal which joins glass and metal surfaces. They are very important elements in the construction of vacuum tubes, electric discharge tubes, incandescent light bulbs, glass-encapsulated semiconductor diodes, reed switches, glass windows in metal cases, and metal or ceramic packages of ...

[citation needed] Early versions produced by McKee Glass Company and Jeannette Glass Company (both of Jeannette, PA) are a type of uranium glass that will glow under UV light. [citation needed] While McKee Glass was the first to produce tableware in this jadeite color glass, the history of this color dates back to the 19th century.
