Uranium Glass Collector Hats

Uranium glass looks mundane until a black light hits it and the piece glows an intense green. It is fairly easy to find in vintage and thrift stores, which is why collectors walk into antique malls carrying a UV flashlight, and a few carry a Geiger counter. One collector measured a piece at 193 counts per second against 6 for an iPhone 15. These uranium glass collector hats are for that crowd. About 4 million pieces were made in the United States between 1958 and 1978, according to Oak Ridge Associated Universities, and uranium content runs from under 1 percent to as much as 25 percent by weight. The U.S. Nuclear Regulatory Commission has said there is no recognized danger in handling or using it, though most collector sites advise against eating or drinking from it, which is the deadpan behind SAFE TO EAT OFF? PROBABLY. The glass has its own vocabulary: vaseline glass is the lighter yellow subset, canary glass and Burmese glass are cousins, and the hunt is half the hobby. Two badges, URANIUM GLASS COLLECTOR and VASELINE GLASS, carry the plain search terms. Searches for hats and shirts on this topic turned up almost nothing, only the glass itself. Every design is custom embroidered on an unstructured dad hat. Wear one to the antique mall with the blacklight in your pocket.
