This pretty green glass formed as a result of the Trinity Nuclear Test near Alamogordo, New Mexico on July 16, 1945. Although it is radioactive, it is safe to handle and valued by collectors. Chemically, trinitite is mostly fused sand, or silicon dioxide. It is quartz with feldspar and various impurities.
While you might think Trinity or any atomic bomb would simply glass over the surface, it’s theorized trinitite formed when sand was sucked up into the nuclear fireball and fell as molten glass, like extremely hot radioactive rain.
Why Trinitite Is Green or Red
The desert sand formed green trinitite. Black trinitite contains iron from the metal tower constructed for the test, while extremely rare red trinitite gets its coloring from the actual device or the cables that led away from it. It’s illegal to remove trinitite from the test site, but there is material in circulation that was taken before the prohibition.
Where To Get Trinitite or Alamogordo Glass
It’s illegal to collect trinitite fro the old test site, but you can purchase specimens that were collected prior to the ban. You can find them at assorted museums and online. I bought a piece when I visited the Nevada Test Site. Amazon sells them, too:
How Radioactive Is Trinitite Today?
The sample I have sits on my desk. Sometimes I pick it up and look at it, although I have not had the courage to use a Geiger counter app on my phone to test it. Will it give me cancer or mutate me into a superhero? You be the judge:
