Uranium Doped
Radioactive Marbles

Uranium Doped Glass Marbles
under normal light

Uranium Doped Glass Marbles
under Ultraviolet light (Blacklight)

Radioactive Uranium Doped Glass Marbles, approximately 5/8" in diameter.
The
marbles contain approximately 3% Uranium 238 ( by weight ).
This small amount of Uranium is added to the glass while it's still in the furnace and in a molten state.
As the Uranium dissolves into the red-hot glass, it takes on the tell-tale pale green color of Uranium Glass.
Because of the added Uranium in the glass,
the marbles
glow brightly under Ultraviolet light ( Blacklight ).
The small amount of radiation that the
marbles
emit will also register on sensitive Geiger Counters.
The
marbles
do not emit high or dangerous levels of radiation, and are completely safe to handle.
A small sample of Uranium ore (the type used to make this particular type of glass) is included. 

Collectors take note: Uranium Glass is no longer manufactured anywhere in the World. Although a few glass manufacturers still have small quantities that they are keeping for historical purposes, no one plans on manufacturing any in the future. Once our stock is sold out, we never expect to see any again.
