Trinitite is produced with an Atomic blast because of the extreme heat causing the sand to melt in to a lightly green tinted glass. Named after the Tinitity Bomb test that happened in New Mexico on July 16, 1945. samples of Trinitite are incredibly scarce because all but a little of the trinitite was buried and is illegal to remove from the site. Our trinitie sample comes encased inside a 4″ x 5″ plastic frame and is suitable for display.
