![]() You would need to test your glassware with XRF testing to know if it contains Arsenic. Not all Depression glass should be presumed positive for Arsenic, as Tamara’s testing (linked to below) shows a set of clear glassware that didn’t test positive for Arsenic. Burgoon, a Toxicologist, explains that without knowing how much arsenic there is in the glass, and studies or testing to show how much leaches out with normal use, it’s not possible to assess the risk. Only one study looks at Arsenic released by the glass, but this is only showing us the leaching at 121 degrees C, which is hotter than the temperature water boils at. It was used to reduce the bubbles that formed as the ingredients were being melted, says the National Depression Glass Association.Īlthough some of it volatilizes out in production, about 50% does remain ( source). ![]() Regardless of if the glass was leaded or unleaded, Arsenic was added to most glass formulas at this time. Green Depression Glass which is Very Likely to Contain Uranium That’s equivalent to the radiation from a 1-hour plane flight in one year”. Burgoon explains that “they will still only see at most an exposure of 0.2 mrem/year. In the case where someone is handling collectible glass (not eating or drinking from it), Dr. That’s also 5,000x less than the radiation from a single chest X-ray ( EPA)”. That’s about 100x less than the radiation dose per hour flying in an airplane. Lyle Burgoon about this and he explained that based on the Nuclear Regulatory Commission‘s data, “drinking from Uranium glassware would result in fairly negligible exposures to uranium – 0.002 mrem/year. Environmental Protection Agency (EPA) recommends against eating or drinking from Uranium glassware.īut because the glass only contains a small amount of Uranium, many websites argue that this glass is safe to eat off of. Jeannette was known for its iridescent Floragold. If it is positive for Uranium it will fluoresce (glow) from the UV exposure. Indiana Glass made bowls, plates, and tumblers in crystal and amber, but rare blue pieces occasionally turn up. You can test your glassware for Uranium by exposing it to UV light (i.e. Here are just a few of those names: Deep Purple, Amethyst, Plum, Violet, Lilac. Some colors of Depression glass contain Uranium Uranium gives glass a yellow or green color, and is referred to as Uranium Glass. Collectors classify purple glass by name, depending on the intensity of the hue.
