A: Vaseline glass is a specific type of uranium glass. It got its name from its distinctive yellowish color, which looks like petroleum jelly. It is also sometimes referred to as canary glass because of its yellow color.
For hundreds of years, glassmakers used small amounts of uranium to create yellow or green glass. The yellow tint of this glass led to the nicknames “Vaseline glass” and “canary glass.” Under an ultraviolet (UV) or “black” light, the uranium causes the glass to glow bright green.
As of 2014, a few manufacturers continue the vaseline glass tradition: Fenton Glass, Mosser Glass, Gibson Glass and Jack Loranger. U.S. production of uranium glasses ceased in the middle years of World War II because of the government's confiscation of uranium supplies for the Manhattan Project from 1942 to 1958.
Uranium glass, an older and more general term, is sometimes used as a synonym for Vaseline glass, but this can lead to confusion because some types of glass colored with uranium (e.g., custard glass and Burmese glass) are opaque whereas Vaseline glass is transparent.
Neither you nor your customers are at risk from the radiation given off by uranium in Vaseline glass, whether they're holding the piece or it's just sitting on a shelf or table. Neither you nor your customers are at risk from uranium if you accidentally ingest or inhale dust or small chips that happen to break off.
From circa 1943 until 1958, because of the events of World War II and the Cold War, U.S. officials did not allow the production of uranium glass since the government had banned uranium salts from commercial use. Only after uranium oxide was deregulated did the U.S. government allow uranium glass to be manufactured.
There was a ban on the production of Vaseline glass from 1943 to 1958, and after the ban was lifted, uranium prices were higher due to its use as a power source. This made the production of new Vaseline glass more expensive.
When this is done, the glass turns a bright florescent green! Sometimes, even the most trained eye can be fooled by a piece of glass that looks like vaseline glass, but without the addition of uranium, the glass will not 'glow' or fluoresce bright green under a blacklight.”
Uranium glass is considered safe to wear and handle, according to the U.S. nuclear Regulatory Commission. In fact, it is considered to be safer than household electronics.
During a bout of pleurisy (a condition often caused by the flu virus, in which the tissue 'twixt lung and chest wall becomes inflamed, causing difficulty breathing), Chesebrough had his nurse cover and rub him, head to foot, in Vaseline. He soon recovered.
Interestingly, new uranium glass is still being produced today, although very few manufacturers are left.
“However, when uranium is exposed to water and air in the natural environment, it 'rusts' and forms uranium oxides,” Verbelen continues. “When those oxides combine with other elements, they form minerals that do glow in the dark, with a little bit of 'help'.”
Uranium glass, also known as Vaseline glass, has a distinct green or yellow-green color due to the presence of uranium oxide. It can be identified by its color under normal light, but the most definitive test is to expose it to ultraviolet light.
Only by testing with the black light will a piece be verifiable. Vaseline Glass can be yellow, yellow-green, or green. Individual collectors each have their own preference as to the exact color of Vaseline glass collected.
It was originally called 'Wonder Jelly', and Chesebrough decided to rebrand the product as Vaseline® Jelly – a combination of the German word for water (wasser) and the Greek word for oil (oleon). And so in 1872 the brand Vaseline® Jelly was born.
Uranium glass is still available to buy today, with some manufacturers continuing to make it and plenty of uranium glass antiques on the market. In fact, people often find uranium glass for sale as normal glassware, as sellers are not aware of what they have.
Uranium glass contains from about 0.25% to 2% uranium. A popular brand of uranium glass is Vaseline glass. So named because in ordinary light it has approximately the color of Vaseline. Under black light it fluoresces bright green.
Even today, so-called “Rosaline glassware” is still made in acrylic glass production. Selenium is also used to color church windows and light-absorbing “privacy glass” (such as tinted windows in cars).
Uranium glass was produced regularly until just before WWII, when the US government halted production as uranium became highly regulated. This moratorium lasted until 1958, when uranium oxide was deregulated, and uranium glass has continued to be produced ever since (Collector's Weekly n.d.).
Genuine sea or beach glass comes from discarded bottles, tableware, or household items and is found in oceans, lakes, and rivers. Genuine sea or beach glass tends to have: Lettering, embossed images, and distinguishing features such as handles, bottle necks, etc.
Technically, uranium glass is radioactive—but at such a low level, it won't harm you from ordinary handling or from living with pieces on display. In fact, in 2001, the US Nuclear Regulatory Commission published a report stating that uranium glass is considered safer than most household electronics.
Yes, there is a difference between uranium glass and Vaseline glass. Uranium glass is a blanket term for any glass containing uranium. Vaseline glass is a specific type of uranium glass with a distinctive yellow color and transparency.
Moisturizing. Petroleum jelly is an oil-based product that forms an oily film over the surface of the skin. This oily film seals in moisture, helping keep skin hydrated and soft. According to a 2016 review article, Vaseline prevents more than 98% of water loss from the outer layer of the skin.
