Wallace T. Smith Collection

Wallace T. Smith collected these specimens between 1947 and 1950 while working for the Sandia Research Laboratory. His collection has been documented in the book "Trinitite, the Atomic Age Mineral" by W.M. Kolb. The specimens pictured here are part of my personal collection. These are all featured in the display that we use at shows and club events and will eventually be part of the museum permanent display. None of these specimens are for sale.


Most of the trinitite in the Wallace T. Smith collection is light to dark green, some with a brownish hue. The specimen pictured above left was the only piece I obtained with red in it. Above right has a bit of black at the top of the specimen. I found several more nice black pieces pictured below. Red piece: 2.3 gms. Black piece: 1.2 gms.

The above piece of trinitite is rare. It has an unexplained blue color in the center of the piece. I have read several books that explain the coloration in red and black trinitite, but none explain the blue. Blue piece: 3.2 gms.
