Trinitite, Atom Bomb Glass, Micromount Sample

Adding to cart… The item has been added

Trinitite was formed during the historic Trinity test of the world's first atomic bomb. Large amounts of desert sand and debris were vaporized into the mushroom cloud and the ground below was liquified into blobs. These blobs cooled and solidified into Trinitite. Collection of new Trinitite samples is now prohibited and access to the old testing site is blocked. The only Trinitite on the market is old stock from before the 1950's ban. This material is safe to own (stored properly) because the most dangerous isotopes have a short-life and they have since degraded into less-harmful decay products. 

The specimen being offered here is a single fragment that comes with an ID label and acrylic gemjar. Note, each piece of trinitite is unique and your sample may vary slightly in appearance from the one shown. It will be of similar size.

Refer to the photo. The black centimeter cube is shown for scale and is not included.

A few more words about the safety and legality of Trinitite :

All of the most harmful radioactive materials in Trinitite have long since decayed into less-harmful decay products. Trinitite emits very little radioactivity now and the majority of it is blocked by the gemjar container. For more information about the history and safety of trinitite, see my Trinitite FAQ file -

Just to be clear for everyone - it is legal to own this material and it is legal to sell this material. It is *not* legal to go to the Trinity site today, hop the fence, and dig up more material. All of the Trinitite on the market was gathered before the prohibition

CAUTION - Keep trinitite away from children, pets, or curious hands. This is considered a collectible for advanced mineral collectors of radioactive ores and related materials.
