This is similar to the quasicrystal found in trinitite, soil fused into a glassy substance by the test-detonation of the Trinity atomic bomb about a month before Hiroshima. When the B-29 bomber Enola Gay flew over Japan and dropped an atomic bomb on Hiroshima on the morning of August 6, 1945, a blast force equal to 20,000 tons of TNT obliterated half the city. Hiroshima was one of two cities devastated by an atomic bomb during World War II, the first and only war in which nuclear weapons were used. They extracted several of them from the surrounding glass for further examination using X-ray diffraction to make out their molecular and atomic structure. Like the metal alloy in hiroshimaites, it was also discovered by Bindi inside particles of glass and metal known as trinitites.
