Collecting Radioactive Vaseline glass not as dangerous as it sounds
By Larry LeMasters
Some collectible items are more dangerous to collect than other items. For instance, Vaseline glass, which was popular in the late 1800s and early 1900s, was made with unstable, radioactive uranium. The proportion of uranium found in Vaseline glass varies from about 2 percent uranium by weight to up to 25 percent uranium by weight.
