Trinitite Green Black Bleb Atomic Glass - 1.28 g

The Atomic Blast That Changed the World:  The Trinity Test

Rare, historic, and legally sourced, this green with black Trinitite specimen with a rare bleb is a genuine artifact from the first-ever nuclear explosion in Alamogordo, New Mexico. Created in the fury of the 1945 blast, it represents the pinnacle of Manhattan Project history and the dawn of the Atomic Age.

Forged when the heat of the "Gadget" vaporized its steel tower and fused the desert sand into glass, this specimen is more than a mineral—it is a frozen second of history. Each piece features the signature vesicular texture created only by the extreme temperatures of a nuclear detonation.

Why does this Trinitite have a Domed Bleb? 

The small black, domed bleb visible in this Trinitite formed during the earliest moments of the Trinity nuclear detonation, when extreme temperatures instantly melted desert sand and trace minerals at the ground surface. Within this chaotic melt, denser, iron-rich material liquefied and briefly separated from the surrounding silica-rich glass, forming a rounded droplet under surface-tension forces. This behavior is consistent with limited melt immiscibility, in which compositionally distinct melts momentarily segregate under extreme thermal conditions. As the fireball expanded and cooled in milliseconds, the droplet was rapidly quenched in place, preserving its smooth, fascinating dome-like shape. Features of this type are uncommon and record localized melt segregation and rapid cooling conditions unique to nuclear-formed glass.
